IL6 and peritonitis: Multivariable linear regression showed that after adjustment for age, gender, DM, serum albumin, hs-CRP, previous peritonitis episode and historical glucose exposure, PD duration (β = 0.176, P = 0.049) had a positive correlation with baseline dialysate IL-6 AR, while 24h urine volume (β = −0.235, P < 0.001) had a negative correlation with baseline dialysate IL-6 AR after being corrected for multiple testing (see Table 3).
