Note: ESRD, end-stage renal disease; PD, peritoneal dialysis; BMI, body mass index; Hb, haemoglobin; hsCRP, high-sensitivity C-reactive protein; Kt/V, solute clearance as a dialysis adequacy index; rGFR, residual glomerular filtration rate calculated by mean of creatinine and urea clearance.
Characteristics are presented as the mean ± SE or as median (interquartile range) for continuous variables and percentages for categorical variables.
a
p<0.05, vs no peritonitis group.
b
p<0.05,vs Gram-positive peritonitis group.
