ALB and susceptibility to pneumonia measurement: On multivariate analysis, independent predictors of pneumonia occurrence in CAPD patients with DN were high body mass index (hazard ratio [HR], 1.15; 95% confidence interval [CI], 1.01–1.31; P = 0.037) and low serum albumin level (HR, 0.87; 95% CI, 0.78–0.98; P = 0.014).
