Predictive value of complete blood cell count-based inflammatory markers for peritonitis risk in peritoneal dialysis patients: A multicenter cohort study.

The median age was 51.0 years, 55.01% were male, and median dialysis vintage was 49.47 months.

Diabetes prevalence was 21.02%.

Over the follow-up, 147 patients (7.22%) developed peritonitis.

Among the indices evaluated, PIV, SII, and platelet-to-lymphocyte ratio showed significant nonlinear associations with peritonitis risk (all P < 0.05).
