Probability, proof, and clinical significance

[摘要] A study reports that treatment A “provided significantly better pain relief” than treatment B. How do you know if the effect is real or due to chance? Assuming that the difference between treatment groups on the outcome is statistically significant, does this mean that your patients will have a clinically significant improvement? This article explores these questions as well as provides some additional points to consider when critically appraising and conducting research.
