Clinical characteristics of patients.

Data are shown as median (interquartile range) or number (%). P values were determined using the Mann-Whitney U test or Chi-square test. AKI: acute kidney injury, eGFR: estimated glomerular filtration rate, COPD: chronic obstructive pulmonary disease, INR: international normalized ratio of prothrombin time, NSAIDs: non-steroidal anti-inflammatory drugs, ACE-I: angiotensin-converting enzyme inhibitor, ARB: angiotensin receptor blocker
Clinical characteristics of patients.

数据以中位数（四分位间距）或例数（百分比）表示。P值通过曼-惠特尼U检验或卡方检验计算得出。AKI：急性肾损伤（acute kidney injury），eGFR：估算肾小球滤过率（estimated glomerular filtration rate），COPD：慢性阻塞性肺疾病（chronic obstructive pulmonary disease），INR：凝血酶原时间国际标准化比值（international normalized ratio of prothrombin time），NSAIDs：非甾体抗炎药（non-steroidal anti-inflammatory drugs），ACE-I：血管紧张素转换酶抑制剂（angiotensin-converting enzyme inhibitor），ARB：血管紧张素受体拮抗剂（angiotensin receptor blocker）。患者的临床特征。
