Fig. 4From: Plasma C4 level was associated with mortality, cardiovascular and cerebrovascular complications in hemodialysis patientsAssociation of plasma C4 level with the 3 endpoints in a restricted cubic spline model. Analyses were adjusted for age and PLT with 4 knots at 5th, 35th, 65th, 95th percentiles of C4. Multivariable adjusted hazard ratios (HRs; red line) with 95% CI (pink area) demonstrated the linear association of plasma C4 level with all-cause mortality a, CCEs b and the composite endpoint cBack to article page
