Laboratory and clinical characteristics of participants with improved and unimproved pruritus intensity, at baseline and at follow-up.

NOTE. Data are expressed as mean ± S.D for normally distributed continuous variables; as median (interquartile range) for non-normally distributed continuous variables; and as number (percentage) for categorical variables.Abbreviations: VAS, visual analog scale.*P**Ca×P = Product of albumin-adjusted serum calcium (Ca) and serum phosphorus (P).

注：对于服从正态分布的连续型变量，数据以均值±标准差（mean ± standard deviation, S.D）表示；对于非正态分布的连续型变量，数据以中位数（四分位数间距）表示；对于分类变量，数据以例数（百分比）表示。缩略语：VAS为视觉模拟评分法（visual analog scale）。*：白蛋白校正血清钙（albumin-adjusted serum calcium, Ca）与血清磷（serum phosphorus, P）的乘积记为Ca×P。
