ALB and peritonitis: Multivariable linear regression showed that after adjustment for age, gender, PD duration, serum albumin, hs-CRP, historical glucose exposure and previous peritonitis episode, comorbid with diabetes (β = −0.128, P = 0.038), 24h urine volume (β = −0.192, P = 0.006) and dialysate IL-6 AR (β = −0.144, P = 0.022) correlate (inversely) with UF capacity at enrollment (see Table 2).
