Demographics and clinical data of pre-TIPS cirrhotic patients and healthy controls.

Values are expressed as mean ± SD. TIPS = Transjugular intrahepatic portosystemic shunt; HC = healthy control; M = male; F = female; SD = standard deviation; NCT = number connecting-A; DST = digit symbol test; HE = hepatic encephalopathy; MHE = minimal hepatic encephalopathy.aThe P value for gender distribution in the two groups was obtained by chi-square test.bThe P value for age and neuropsychological tests difference between the two groups was obtained by two sample t test.#The other HE patient died thus unavailable for follow-up MRI studies.数据以均值±标准差（standard deviation, SD）表示。经颈静脉肝内门体分流术（Transjugular intrahepatic portosystemic shunt, TIPS）、健康对照（healthy control, HC）、男性（male, M）、女性（female, F）、标准差（standard deviation, SD）、数字连接试验A（Number Connecting Test A, NCT）、数字符号试验（digit symbol test, DST）、肝性脑病（hepatic encephalopathy, HE）、轻微肝性脑病（minimal hepatic encephalopathy, MHE）。 a 两组性别分布的P值采用卡方检验计算得到。 b 两组间年龄与神经心理学测试结果差异的P值采用两独立样本t检验计算得到。 #其余肝性脑病患者已死亡，无法进行随访磁共振成像（Magnetic Resonance Imaging, MRI）检查。
