Preoperative Patient Characteristics.

Continuous data are reported as mean± SEM or median (25th, 75th percentile). PVD, peripheral vascular disease; ACE, angiotensin-converting enzyme; ARB, angiotensin receptor blocker; AST, aspartate aminotransferase; CKD EPI eGFR, chronic kidney disease epidemiology collaboration estimated glomerular filtration rate.[27]a Mann Whitney U test;b t-test;c Fischer Exact test,d Pearson Chi-Square testPreoperative Patient Characteristics.

连续型数据以均值±标准误（standard error of the mean, SEM）或中位数（25th百分位数至75th百分位数）形式报告。PVD：外周血管疾病（peripheral vascular disease）；ACE：血管紧张素转换酶（angiotensin-converting enzyme）；ARB：血管紧张素受体阻滞剂（angiotensin receptor blocker）；AST：天冬氨酸氨基转移酶（aspartate aminotransferase）；CKD EPI eGFR：慢性肾脏病流行病学合作研究估算肾小球滤过率（chronic kidney disease epidemiology collaboration estimated glomerular filtration rate）。[27]a 曼-惠特尼U检验（Mann Whitney U test）；b t检验（t-test）；c 费希尔精确检验（Fischer Exact test）；d 皮尔逊卡方检验（Pearson Chi-Square test）术前患者特征。
