  • 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. 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 our website https://www.precision-evidence.com

96% of published studies mention a p-value at 0.05 or lower: “What Have We (Not) Learned from Millions of Scientific Papers with P Values?” https://www.tandfonline.com/doi/full/10.1080/00031305.2018.1447512
