Demographics and Clinicopathologic Characteristics of Patients with IgAN.

Values are presented as the means ± standard deviation (SD) if the variables showed a normal distribution and as medians (IQR) if the variables did not show a normal distribution; n (%) was used for the categorical variables.SBP: systolic blood pressure; DBP: diastolic blood pressure; MAP: mean arterial blood pressure; SCr: serum creatinine; BUN: blood urea nitrogen; eGFR: estimated glomerular filtration rate; UA: serum uric acid; Hb: hemoglobin; ALB: serum albumin; UPE: 24-h urinary protein excretion; uRBC/HP: hematuria; TA-ALB: time-averaged serum albumin; TA-SCr: time-averaged serum creatinine; TA-eGFR: time-averaged eGFR; TA-UPE: time-averaged 24-h urinary protein excretion; Peak UPE: maximum level of UPE during follow-up; Peak SCr: maximum level of SCr during follow-up; Minimum ALB: minimum level of ALB; Minimum eGFR: minimum eGFR during follow-up; UPE ratio: (UPE at follow-up—baseline UPE) / baseline UPE.Demographics and Clinicopathologic Characteristics of Patients with IgAN.

数据值以均值±标准差（SD）呈现，若变量呈正态分布；若变量未呈正态分布，则以中位数（四分位数间距）呈现；对于分类变量，使用n（%）表示。SBP：收缩压；DBP：舒张压；MAP：平均动脉压；SCr：血清肌酐；BUN：血尿素氮；eGFR：估计的肾小球滤过率；UA：血清尿酸；Hb：血红蛋白；ALB：血清白蛋白；UPE：24小时尿蛋白排泄量；uRBC/HP：血尿；TA-ALB：时间平均血清白蛋白；TA-SCr：时间平均血清肌酐；TA-eGFR：时间平均eGFR；TA-UPE：时间平均24小时尿蛋白排泄量；Peak UPE：随访期间UPE的最大水平；Peak SCr：随访期间SCr的最大水平；Minimum ALB：ALB的最小水平；Minimum eGFR：随访期间eGFR的最小水平；UPE ratio：（随访期间UPE与基线UPE之差）/基线UPE。IgAN患者的人口统计学和临床病理学特征。
