Body compositionanalyses for predictors of overall survivalby gender groups.

BMI, body mass index; SMI, skeletal muscle index; OS, overall survival; HR, hazard ratio; CI, confidential interval. aPvalues were calculated using the Cox-proportional hazard model, adjusted with age, extent of disease, and PS. Body compositionanalyses for predictors of overall survivalby gender groups.BMI：身体质量指数（body mass index）；SMI：骨骼肌质量指数（skeletal muscle index）；OS：总生存期（overall survival）；HR：风险比（hazard ratio）；CI：置信区间（confidence interval）。 所有P值均采用Cox比例风险模型计算，并以年龄、疾病累及范围及PS进行校正。 按性别分组开展身体成分分析，以探究总生存期的预测因素。
