Hazard ratios for stroke occurrence in lung cancer patients stratified by treatment groups and diabetes mellitus.

Abbreviations: HR, hazard ratio; 95% CI, 95% confidence interval; RT, radiotherapy.
Note 1: All adjusted hazard ratios were estimated by using Cox proportional hazard analysis.
Note 2: Patients in the surgery-alone group without diabetes were as the reference (value = 1).

缩写说明：HR为风险比（hazard ratio）；95% CI为95%置信区间（95% confidence interval）；RT为放射治疗（radiotherapy）。
注释1：所有校正后的风险比均通过Cox比例风险分析估算得到。
注释2：以未合并糖尿病的单纯手术组患者作为参照（赋值为1）。
