Epidemiology is a cornerstone for the practice of evidence-based medicine, but for the sake of medical licensing exams, only the very basics are “high yield knowledge.” Rather than having to sift through PowerPoint slides or a textbook, I compiled a one page handout of must-know-facts for the boards while preparing for USMLE Step 3 (though it still applies to Steps 1 and 2). Hopefully this helps people looking for a quick summary of basic biostatistics. 🙂
There is a mistake in your worksheet. Specificity has NOTHING to do with NPV and Sensitivity has NOTHING to do with PPV. They are unrelated. Please correct that for others.
Sorry you wrote “High Spec = high PPV and High Sens = High NPV” That’s still wrong since sens and spec do no say anything about what the denominator of NPV and PPV will be.
I’ll look into this when I get a chance.
Thank you so much !!!
You’re very welcome, Priya! Hope this helps! 🙂
