NPPB and hydrops fetalis: The direct effect (HR [95% CI], 1.51 [1.25–1.81], P < 0.001) between thicker EAT and higher risk of HF was weakened by the indirect effect through NT-proBNP (HR [95% CI], 0.95 [0.92–0.98], P = 0.011), resulting in a milder total effect (HR [95% CI], 1.43 [1.19–1.72], P < 0.001).
