Figure 2. Association between Gradations of Adiponectin and All-Cause Mortality in Maintenance Hemodialysis Patients.

Figures present log hazard ratios (short-dashed lines indicate 95% CIs) for adiponectin analyzed as a spline with knots at 14 µg/ml (25^th percentile) and 36 µg/ml (75^th percentile). A histogram of observed adiponectin values and a log hazard reference ratio of 0 (long-dashed line) is overlaid. Analyses adjusted for age, sex, race, ethnicity, dialysis vintage, diabetes, serum albumin, total iron binding capacity, serum creatinine, white blood cell count, phosphorus, hemoglobin, and normalized protein catabolic rate.
