Characteristics of spinal anesthesia and incidence of adverse events.

The values are presented as the median (interquartile range), or the number of patients (%) per group.Group NO = non-obese group; Group O = obese group; MBP = mean blood pressure; decrease in MBP = baseline MBP—lowest MBP.a Other variables except these two were analyzed by using data of those with successful anesthesia induction.b p-values are the results of log rank test.Characteristics of spinal anesthesia and incidence of adverse events.数据以中位数（四分位间距）或各组患者例数（百分比）的形式呈现。非肥胖组（Group NO）；肥胖组（Group O）；平均血压（mean blood pressure, MBP）；MBP下降值=基础平均血压－最低平均血压。a 除上述两项外的其余变量，均采用麻醉诱导成功受试者的数据进行分析。b P值为对数秩检验（log rank test）的结果。脊髓麻醉（spinal anesthesia）相关特征及不良事件发生率。
