ALB and pneumonia: Table 3 shows the predictors of pneumonia for CAPD patients with DN. There were no significant variables using univariate Cox regression analysis, however, the multivariate analysis model identified higher BMI and lower serum albumin as independent predictors of pneumonia occurrence after adjusting for age, hypertension, cardiovascular disease, stroke, DBP, MAP, and eGFR. The predictors of pneumonia for the non-DN group are summarized in Table 4.
