The NNT (number needed to treat) is a great resource for EBM.
From the NNT site:
Quick summaries of evidence-based medicine!
We are a group of physicians that have developed a framework and rating system to evaluate therapies based on their patient-important benefits and harms as well as a system to evaluate diagnostics by patient sign, symptom, lab test or study. We only use the highest quality, evidence-based studies (frequently, but not always Cochrane Reviews), and we accept no outside funding or advertisements.
The NNT has a helpful grading system and rigorous standards that make it a lot clearer to discern actual patient benefits and harms.
better yet, as someone starting out in EBM or new to the #FOAM world (like myself), the NNT is a hugely useful resource for understanding how clinical trials work and how to properly interpret their results.
so go have a quick look at the NNT!
