Baseline model includes all patients and uses the baseline NT-proBNP. The 24 h model uses the 24 h NT-proBNP value and excludes 29 patients with an event in the first 24 h postrandomization. The 72 h model uses the 72 h NT-proBNP value and excludes 35 patients with an event in the first 72 h postrandomization. BP Blood pressure
