Notes: PDF levels of sC5b-9, C3, and C4 were adjusted for protein levels in PDF. The logistic regression models were adjusted for PD history and serum albumin levels. PDF, peritoneal dialysis fluid; OR, odds ratio; CI, confidence interval; NRI, net reclassification improvement; IDI, integrated discrimination improvement; WBC, white blood cells.
