The change in NT-proBNP was poorly correlated with change in SBP ( LCZ@ , r = @ , P = @ ; valsartan , r = @ , P = @ ) After adjustment for change in SBP , the ratio of change in NT-proBNP at @weeks for LCZ@ vs. valsartan was @ ( @ % CI @-@ @ , P = @ ) , and similar to the ratio not adjusting for SBP ( @ , @ % CI @-@ @ , P = @ ) ; P for interaction was @ ) .
