Data are presented as the mean±SD, n, or median (25th percentile, 75th percentile). The significance of differences at baseline was assessed using the unpaired t test. The significance of the effect of fiber was assessed using analysis of covariance. CRP, C-reactive protein; KDQOL-36, Kidney Disease Quality of Life Short Form 36.
a
Six CRP values were <0.1 mg/dl (the limit of quantitation), but no participant had a value <0.1 mg/dl at both baseline and week 6.
b
One patient in the fiber group and four patients in the control group did not complete the KDQOL-36 at the end of the study.
