Each participant’s change score of pruritus intensity = follow-up VAS score of pruritus intensity – baseline VAS score of pruritus intensity. Similarly, each participant’s change score of a covariate = follow-up data of a covariate – baseline data of a covariate.</p><p>Abbreviations: AST, aspartate transaminase; VAS, visual analog scale.</p>*<p>Ca×P = Product of albumin-adjusted serum calcium (Ca) and serum phosphorus (P).</p>1<p>Model considered only the covariates measured at baseline (gender, Kt/V, use of high-flux dialyzer, pruritus intensity, hematocrit, creatinine, uric acid, fasting glucose, total bilirubin, Ca×P). <i>R</i><sup>2</sup> = 0.736.</p>2<p>Model considered both the covariates measured at baseline (Kt/V, pruritus intensity, AST, Ca×P) and the change scores of the covariates (uric acid, fasting glucose, AST). <i>R</i><sup>2</sup> = 0.752.</p>
