Everyone wants it; clinicians aim to deliver it. We rely on randomized trials for evidence of treatment effects, but randomized trials typically report "overall" benefits and harms averaged across heterogeneous patients. This practice might facilitate medicine, but not personalized medicine. The traditional next step toward personalizing trial results has been subgroup analyses, but these are fraught with false-negative and false-positive results (1). Current approaches for trial reporting often fail to inform the individual patient and his or her physician of the best treatment choice.In their articles on ...References1. Lanza ST, Rhoades BL.
