P * - statistical significance for differences between HD A, HD B, PD and CKD groups, TE and C for quantitative variables - Kruskal Wallis ANOVA, one-way ANOVA or Student’s t test

P ** - statistical significance for differences between HD A, HD B, PD and CKD and TE groups for Kruskal Wallis’s ANOVA quantitative variables or ANOVA one-way analysis

Kt / V - dialysis index (volume fraction V purified by clearance K at time t)

NS no statistically significant relationships were found
