When the model was adjusted for all confounders (age at alloSCT, sex, body mass index, hypertension, smoking status, diabetes, history of ACS, creatinine, cancer diagnosis, and type of conditioning regimen), log-transformed NT-proBNP (HR: 1.21 [95% CI: 1.11-1.31], P < 0.001) and NT-proBNP ≥125 ng/L (HR: 1.29 [95% CI: 1.04-1.60] P = 0.020) were positively associated with an increased risk of mortality (Central Illustration). Here, NPPB is linked to hypertensive disorder.
