Baseline characteristics of all 140 patients.

All continuous values expressed in median (range).ALT, alanine aminotransferase; ULN, upper limit of normal; HBsAg, hepatitis B surface antigen.ALT upper limit of normal: 30 U/L for men, 19 U/L for women.*Comparison was between patients with ALT ≤2×ULN and ALT >2×ULN.所有连续型变量均以中位数（范围）表示。丙氨酸氨基转移酶（alanine aminotransferase，简称ALT）、正常上限（upper limit of normal，简称ULN）、乙型肝炎表面抗原（hepatitis B surface antigen，简称HBsAg）。丙氨酸氨基转移酶的正常上限为：男性30 U/L，女性19 U/L。*本次比较的对象为丙氨酸氨基转移酶≤2倍正常上限与＞2倍正常上限的患者。
