Correlation coefficients between pretreatment solute levels after adjusting for the effect of Kt/V_urea on both solutes (partial correlation coefficients). Subjects with recorded urea reduction ratio >94% (n=17) or <5% (n=2) were excluded, because it was presumed that they represented error in sample collection or labeling. UN, urea nitrogen.
