Null and noteworthy
The true meaning of a null result
This edition of Null and Noteworthy highlights results that reveal the difficulty in drawing definitive conclusions from data, including new findings about epidurals that contradict several others and an apparent null result on sex differences that may derive from “circular logic.”
