Univariable and multivariable analysis of risk factors for mortality.

For univariable analysis, separate models were used for GMFCS subgroups, associated impairments/seizures, and severe malnutrition. These parameters were also included in one single multivariable model.在单变量分析中，针对GMFCS亚组、伴随损伤/癫痫发作以及重度营养不良分别构建了独立模型。上述参数亦被纳入单一的多变量模型中。
