Fig. 2From: Range of plasma brain natriuretic peptide (BNP) levels in hemodialysis patients at a high risk of 1-year mortality and their relationship with the nutritional status: a retrospective cohort study in one instituteEstimated cubic spline transformation of the relationship between BNP levels and the adjusted hazard ratio. The reference BNP for this plot (with HR fixed as 1.0) was <50 pg/mL. The hazard ratio of 1-year mortality was adjusted for age, gender, dialysis vintage, and primary diseases.
