按围术期血糖状态分层的ESCC根治术患者基线特征
Selected characteristics of ESCC patients who underwent radical esophagectomy, stratified by perioperative glucose status
| Characteristics | Total(n=5 952) | Preoperative hyperglycemiaa | Postoperative hyperglycemiaa | |||||
| No (n=5 341) | Yes (n=381) | P valueb | No (n=3 796) | Yes (n=848) | P valueb | |||
| Data are M (P25, P75) or n(%). BMI, body mass index; ESCC, esophageal squamous cell carcinoma; pStage, pathological stage. a, due to missing preoperative or postoperative glucose measurements in some patients, the sum of cases across groups does not equal the total sample size; b, categorical variables were compared using the Chi-square test, and continuous variables were compared using the Student’ s t test; c, the sum of the number of patients in different categories is not equal to the total sample size because of the existence of missing values. | ||||||||
