IQR, interquartile range.*Characteristics measuring duration of interruptions and duration of treatment episodes were averaged within each patient; values in the table represent the median and IQR of these averages.IQR即四分位距（interquartile range）。针对衡量中断时长与治疗疗程时长的特征指标，我们在每位患者内部对其取值进行平均计算；表格中的数值为这些平均值的中位数与IQR。
