35.5 (5.2)

34.7 (5.5)

LS mean change at Week 24 (SE)a

-0.5 (0.4)

-1.1 (0.5), p =.307

-0.4 (0.4), p =.929

LS mean change at Week 48 (SE)a

0.1 (0.6), p =.631

  1. aThe LS mean change from baseline, standard error, and p-value for the difference between each of the tadalafil groups minus placebo are derived using ANCOVA with factors for treatment and baseline echocardiogram measure as covariate
