"Types of study design" (x), развернутый конспект.

There are literally thousands of ways to design a study. When a news story suggests, "A new scientific study has found..." or a celebrity doctor begins a sentence with, "Studies show...", you need to ask, "What kind of studies?" Because "studies" are not equally reliable, they all have different limitations, and they should not be acted on in the same manner — or even acted on at all.

"Research study hype" (x), выдержки.

In 2003, researchers writing in the American Journal of Medicine discovered something that should change how you think about medical news. They looked at 101 studies published in top scientific journals between 1979 and 1983 that claimed a new therapy or medical technology was very promising. Only five, they found out, made it to market within a decade. Only one (ACE inhibitors, a pharmaceutical drug) was still extensively used at the time of their publication.
