Figure 1 Flowchart of the retrospective patient selection processThe flowchart illustrates patient identification, screening, and inclusion for laparoscopic sleeve gastrectomy during the study period. A total of 1708 patients were initially identified from the integrated perioperative data platform. Patients were excluded according to predefined criteria, including incomplete baseline laboratory data (>60% missing), pre-existing end-stage renal disease, and missing outcome information. The final analytical cohort consisted of 1386 patients and was included in all subsequent analyses. No outcome-driven exclusion or post hoc filtering was applied.
