  • The test size. Has got the scholarly research been carried out on 10, or 10,000 individuals? (for a few research purposes, an example measurements of 10 is enough, but also for most studies bigger is much better).

This permits us to raised determine the essential documents in a specific field, see in the event that writers cited my personal documents (KIDDING!….mostly), and locate types of helpful some ideas or strategies.)

IMPROVE: if you’d like to see a good example of how exactly to read a science paper utilizing this framework, you will find one right here.

We gratefully acknowledge teachers José Bonner and Bill Saxton for teaching me personally simple tips to critically read and evaluate clinical documents utilizing this process. I’m honored to have the opportunity to transfer what they taught me personally.
