  • 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. As we go beyond the abstract in this podcast, we have created a screening tool you can use when reading an abstract from a clinical research paper.

Using that tool enables you to quickly screen an abstract from a medical journal for clinical relevance selecting only those you want to read. At the same time, you will know why you skipped the rest. Get it at https://www.precision-evidence.com/tool

NOTES:

 We only have limited information about the new Covid-19 vaccines released by press releases

  • Unfortunately, there is a broad misunderstanding of how to interpret the efficacy measures and what they mean
  • What is an efficacy value, and what can we learn from that?
  • We only have the raw measures of efficacy without confidence intervals
  • Efficacy versus efficiency and why it matters
  • Based on data from the press releases, we cannot make a valid calculation of how many people need to be vaccinated to prevent one case of covid-19
  • But we do it anyway…
  • Estimating how many people need to be vaccinated to prevent one case of covid-19 based on the data we have (the Number Needed to Treat or NNT values)
  • Are these values good?
  • Finding clinical relevance and meaningfulness with using the Precision Evidence Matrix
  • Press releases versus future medical papers
  • What are we missing?
  • Comparison between different vaccine trials
  • We will follow up when the research papers are published
