2. Figure 1
Repeated-measures analysis of variance, P values for group effect, time effect, and interaction are depicted. A, Plasma concentrations of IL-6, stratified by groups A, B, C, and D. Asterisk indicates P < .005 for groups A and B; section mark indicates P < .01 for group C versus group D. B, Plasma concentrations of IL-10, stratified by filter types PAF and PSF. Asterisk indicates P = .0002; double asterisk indicates P < .001 for PAF. C, Plasma concentrations of TNF, stratified by ultrafiltration methods CUF and MUF. Asterisk indicates P < .002 for MUF. D, Plasma concentrations of TCC, stratified by filter types PAF and PSF. Asterisk indicates P < for PAF. E, Plasma concentrations of lactoferrin (LF), stratified by groups A, B, C, and D. Asterisk indicates P < .005 for A.

A, Ultrafiltrate (UF) concentrations of TNF in groups A, B, C, and D. Asterisk indicates P < .02. B, Ultrafiltrate/plasma ratio of IL-6 in groups A, B, C, and D. Asterisk indicates P < .02; double asterisk indicates P < .01.
