NPPB and ganglioneuroma: An increased NTproBNP above the 400 pg/ml threshold was associated with a statistically significant increased risk of the composite primary outcome in all GN sub-groups: IgAN HR 1.84 (95% CI, 1.62, 2.09); MN HR 1.91 (95% CI, 1.68, 2.18); FSGS HR 1.88 (95% CI, 1.65, 2.14) and MCD HR 1.77 (95% CI, 1.56, 2.00).
