Enhanced recovery after surgery protocol implementation in pediatric Meckel’s diverticulum resection: A clinical outcome study

Figure 3 Comparison of postoperative length of stay. A: Implementation of enhanced recovery after surgery resulted in a significant reduction in length of stay; B: Subgroup analysis by surgical approach showed the greatest length of stay reduction in patients undergoing segmental resection; C: Standardized mean differences of covariates before and after inverse probability weighting. Covariates included in the models: Age, weight, American Society of Anesthesiologists classification, surgical approach, and surgical indication/disease severity. ^bP < 0.001. LOS: Length of stay; ERAS: Enhanced recovery after surgery; TRAD: Traditional care group; SMD: Standardized mean difference; IPW: Inverse probability weighting.
