Relationship between duration of exposure and valvular regurgitation. a) Prevalence of mild or greater aortic regurgitation (AR), mitral regurgitation (MR), and tricuspid regurgitation (MR) as a function of duration of fenfluramine use. P-values are for one-sided trend test. b) Prevalence of moderate or greater aortic regurgitation (AR), mitral regurgitation (MR), and tricuspid regurgitation (MR) as a function of duration of fenfluramine use.
