nominally significantp =0.03
9 A nominally significant interaction between NYHA class at randomization and the effect of treatment was seen for the primary endpoint (better outcomes with NYHA class I–II; p =0.03; without adjustment for multiple comparisons), but not for the interaction between NYHA class and the effect on death from CV causes ( p =0.76). 9 Although the interaction is nominal, it confers a greater CV benefit to sacubitril/valsartan when initiated early in the course of HFrEF.
