Clinical Trials & Surrogate Outcomes Looking for clinical relevance means looking for a lot of details.  A crucial part of that is looking at WHAT is compared with WHAT But what if a comparison is not clinically relevant  - what do you do then? And how about studies using surrogate outcomes perhaps even approved by the FDA - they must be clinically relevant - but are they? In this episode, we talk about how to navigate this and find the best available research You don’t want to miss this episode    Get the Precision Evidence Newsletter https://bit.ly/3tLBx3Z   LINKS: Assessment of Overall Survival, Quality of Life, and Safety Benefits Associated With New Cancer Medicines Supplemental content, JAMA Oncology (2017) https://jamanetwork.com/journals/jamaoncology/fullarticle/2594542  FDA Approved Surrogate Endpoints: https://www.fda.gov/drugs/development-resources/table-surrogate-endpoints-were-basis-drug-approval-or-licensure   Virtual Reality Smartphone-Based Intervention for Smoking Cessation: Pilot Randomized Controlled Trial on Initial Clinical Efficacy and Adherence https://www.jmir.org/2020/7/e17571/    NOTES:  Finding clinically relevance in what is compared with what in a clinical trial  How can we know what a relevant comparison is?

Addressing Clinical Relevance in Medical Papers Clinical trials and research should always aim to provide information that is meaningful and relevant for patients. In the last episode, we looked at how many - or rather - how few researchers mentioned and argued for what they would see as clinically relevant outcomes when setting up a study and listing it on clinicaltrials.gov In this episode, we go deeper to look at examples and why this is so important to improve the usefulness of the research   We want to make it mandatory to state the researchers' clinical relevance levels ahead of the trial, mentioning what they will consider clinically relevant when they pre-register their research on the clinicaltrials.gov website or similar websites. They then need to compare their findings in both the paper and abstract when publishing data from the study.    #clinicalrelevance   LINKS: Once-Weekly Semaglutide in Adults with Overweight or Obesity Paper https://www.nejm.org/doi/full/10.1056/NEJMoa2032183  ClinicalTrials.gov: https://clinicaltrials.gov/ct2/show/study/NCT03548935  10-Year Update on Study Results Submitted to ClinicalTrials.gov  https://www.nejm.org/doi/full/10.1056/NEJMsr1907644 FDA and NIH let clinical trial sponsors keep results secret and break the law https://www.sciencemag.org/news/2020/01/fda-and-nih-let-clinical-trial-sponsors-keep-results-secret-and-break-law  Compliance with the legal requirement to report clinical trial results on ClinicalTrials.gov: a cohort study https://www.thelancet.com/pdfs/journals/lancet/PIIS0140-6736(19)33220-9.pdf  Our specific page on our website about requesting clinical relevance statement and evaluation https://www.precision-evidence.com/p/clinical-relevance/  Overview of clinical trials registers like clinicaltrials.gov: https://sites.google.com/a/york.ac.uk/yhectrialsregisters/home/clinicaltrials  Precision Evidence episode 11: “Clinical relevance - Looking at Recent Papers”  https://www.precision-evidence.com/11  NOTES:   Why is stating levels for clinical relevance important to make before a clinical trial starts?

Clinical trials and research should always aim to provide information that is meaningful and relevant for patients. However, researchers are rarely addressing that topic when presenting results from trials. In this episode, we look at published papers from high-ranking journals to get a sense of the extent of that problem.  You may be surprised by our findings...   We want to make it mandatory to state the researchers' clinical relevance levels ahead of the trial, mentioning what they will consider clinically relevant when they pre-register their research on the clinicaltrials.gov website or similar websites. They then need to compare their findings in both the paper and abstract when publishing data from the study.    #clinicalrelevance   LINKS: Our specific page on our website about requesting clinical relevance statement and evaluation https://www.precision-evidence.com/p/clinical-relevance/  Overview of clinical trials registers like clinicaltrials.gov: https://sites.google.com/a/york.ac.uk/yhectrialsregisters/home/clinicaltrials  Precision Evidence episode 10: “How to Get to Clinically Relevant Research” https://www.precision-evidence.com/10    NOTES:  Statistical significance vs. clinical significance in clinical research Clinical significance, clinical relevance, clinical meaningfulness, clinical evidence Why researchers in the clinical field should always note ahead of starting a trial what they would consider clinically relevant and then refer back to that in the paper and abstract Looking at 44 papers published in early 2021 in high ranking journals and analyzing the mentioning of clinical relevance It is disappointing....

How to Get to Clinically Relevant Research The default method to evaluate clinical research is by statistical significance  Unfortunately is statistical significance not related to the meaningfulness of the findings in the research and thereby to its meaningfulness for patients and healthcare If researchers stated ahead of starting the trial what they would consider clinically relevant,  the reader could relate to that and agree or disagree with the researcher It would come from focusing on using the provided information to help patients and improve healthcare - and not just publishing a paper We want to make it mandatory to state the researchers' clinical relevance levels ahead of the trial, mentioning what they will consider clinically relevant when they pre-register their research on the clinicaltrials.gov website or similar websites. They then need to compare their findings in both the paper and abstract when publishing data from the study.    #clinicalrelevance   LINKS: A specific page on our website about requesting clinical relevance statement and evaluation https://www.precision-evidence.com/p/clinical-relevance/  The history behind the chosen level for statistical significance with Ronald Fisher's book from 1925 "Statistical Methods for Research Workers."

Critical Appraisal of the Moderna COVID19 Vaccine Trial There is a big interest in clinical research now due to the Covid19 pandemic Especially the trails behind the Covid vaccines gain interest and is all over the news In this episode, we take a look at the published paper on the Moderna vaccine trial using our last episode of this podcast (#7) about the precision of the evidence We know from the news that the outcome in the Moderna vaccine trial is good with a reduction in risk at 94.1% by getting the vaccine But is the study as a whole clinically relevant and trustworthy? And how many people need to be given the vaccination to prevent one COVID19 infection? - Probably not what you would guess We will cover this and much more in this episode GET THE ABSTRACT SCREENING TOOL It can be a challenge to screen papers for clinical relevance.

You’ve probably often heard that “Clinical trials show..” or “ evidence support that..” Unfortunately, a research paper being published in a peer-reviewed medical journal is NOT a guarantee that it is clinically relevant  - even if it is a high ranking journal As it is often the case the devil is in the details, so it is necessary to both read and evaluate the paper’s details and to put it into the context where you need the information In this episode, we will talk about the details you need to look for     GET THE ABSTRACT SCREENING TOOL It can be a challenge to screen papers for clinical relevance.

Results from clinical trials should be published in medical papers and not evaluated from selected information in press releases We still need a lot of information from the trials to be able to have a clear picture of the efficacy and safety of the Covid-19 vaccines, let alone the precision and clinical relevance of the findings The information presented in the press releases are not sufficient to make calculations on risk But here is what you can find if you do it anyway   GET THE ABSTRACT SCREENING TOOL It can be a challenge to screen papers for clinical relevance.

In the Covid-19 vaccine trials, there is an essential difference between the relative reduction of risk for covid19 provided by vaccination and the absolute risk reduction for the individual person. But can we expect to find that information in the papers referring the trials - and will we be able to compare results between the different vaccines? Furthermore, must the study population in the vaccine trials reflect those expected to benefit from vaccination. And that seems to be a problem too.

The Precision Evidence Podcast is the podcast for those in healthcare interested in finding, evaluating, and using medical research that is meaningful to patients.  Hosted by Dr. Kim Kristiansen, M.D.  https://www.linkedin.com/in/kim-kristiansen - Twitter: @KKristiansenMD A family physician with 30 years of clinical experience, a peer reviewer for medical journals, and former TEDMED research scholar J.G Staal https://www.linkedin.com/in/jgstaal - Twitter: @HealthyEvidence Work in the field of Data Analytics & Data Science. Interested in clinical research as a caregiver and having a hard time making sense of research and, in particular, understanding what is relevant and clinically significant   We want to focus on evaluating clinical research and finding outcomes that are meaningful to patients and applicable to the individual patient. That is what we call Precision Evidence HealthCare is based – or rathe depends - on research. Still, the quality and meaningfulness of the findings and the trials and how they are designed and run are often not relevant or useful from a clinical perspective. What if any health decision would rely on clinically relevant and meaningful information applicable to the individual patient? That’s easier said than done, so this podcast aims to discuss and explore both the need and the ways to find this information / separating the news from the news from the fake news, if you will. Unfortunately, this information can be tough to find. It is not sufficient to read the abstract of a medical paper, let alone the headline or a recap. And even though you can screen a paper by Its abstract - it is crucial to dig deeper into the paper. Evidence in Evidence-Based Medicine has a different meaning in healthcare than in everyday life Not clinically relevant clinical research is a big problem In the Precision Evidence Podcast, we will focus on finding clinically relevant and meaningful research applicable to the individual patient. We will analyze published research and have conversations with people in the field like healthcare professionals, researchers, patients, and caregivers, investors, payers, politicians, regulatory authorities; the list of stakeholders is long Contact us [email protected] Twitter @PrecisionEBM website: www.precision-evidence.com Music thanks to mixkit.co
