Figure 3.

Estimated adjusted hazard ratio (solid line) with 95% confidence intervals (dashed lines) for the association of serum adiponectin level and all-cause mortality. The median adiponectin (ADPN) level was used as a reference point for the calculation of all hazard ratios. Nonlinear relationships were first examined using restricted cubic splines (knots=3; P=0.88 for the test of nonlinearity; P<0.001 for the test of linear relation). The model is adjusted for age, sex, estimated GFR, serum albumin, natural log-transformed C-reactive protein, abdominal circumference, systolic BP, Charlson Comorbidity Index score, malnutrition-inflammation score, and time since kidney transplantation.
