NPPB and Stroke: The risk of stroke/SE was not statistically different across the randomization groups among participants with NT-proBNP ≤15 pmol/L at baseline (HR 1.11 [95% CI, 0.76–1.62]), whereas a significant risk reduction by ILR screening compared with usual care was observed among participants having higher NT-proBNP levels (HR 0.60 [95% CI, 0.40–0.90]; Pinteraction=0.029).
