Fig. 3From: U-shaped association between plasma sphingosine-1-phosphate levels and mortality in patients with chronic systolic heart failure: a prospective cohort studyAssociation between S1P levels and the adjusted hazard ratio for all-cause death. Histograms stand for frequency of patients at different S1P concentrations (The right-hand y-axis). The solid curve gives expected of adjusted HR based on restricted cubic spline analysis (The left-hand y-axis). The dashed curves represent the 95% confidence intervals for expected of adjusted HR (The left-hand y-axis). Model adjusted on MAGGIC score and lgNT-proBNPBack to article page
