a nonsignificant trendP = 0.09
The predictive value of serum TTR levels was also enhanced in populations with higher percentage of HF patients ( P = 0.009) ( Supplemental Figure 4 ), in cohorts with elevated serum creatinine levels ( P < 0.001) and showed a nonsignificant trend in studies with higher percentage of coronary artery disease patients ( P = 0.09) ( Supplemental Figure 5 ).
