研究目的:

通过对脓毒症患者死亡组与生存组以及是否发生脓毒症脏器功能损伤之间的临床特征进行比较分析,寻找脓毒症死亡以及发生脏器功能损伤的危险因素,并构建基于临床数据的预测模型,为临床医生提供脓毒症脏器功能损伤及死亡风险的预警工具,早期干预,早期治疗,从而降低脓毒症患者死亡率。  

Objectives of Study:

This study aimed to identify risk factors for mortality and organ dysfunction in sepsis by comparing clinical characteristics between survivors and non-survivors, as well as between patients with and without organ dysfunction. We further developed prediction models based on these clinical parameters to provide clinicians with early warning tools, potentially enabling timely interventions to reduce sepsis-related mortality.

随机方法(请说明由何人用什么方法产生随机序列):

由两名经过培训的研究人员独立收集数据。采用R语言进行随机分组,设定随机种子数为1234,按7:3的比例将研究对象随机分配至训练集和验证集。所有数据收集和随机分配过程均经过交叉核对,如遇分歧由第三名高级研究者进行裁决。

Randomization Procedure (please state who generates the random number sequence and by what method):

Data were independently collected by two trained investigators. Randomization was performed using R software with a predetermined random seed (set.seed=1234) to allocate patients to the training and validation cohorts in a 7:3 ratio. All data collection and randomization procedures underwent cross-validation, with any discrepancies resolved through adjudication by a third senior investigator.
