What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: This study aimed to evaluate the association between stratified body mass index (BMI) and the intraoperative outcomes and short-term postoperative recovery profiles of patients undergoing single-incision laparoscopic appendectomy (SILA), utilizing a propensity score-matched (PSM) analysis to minimize baseline selection bias and confounding clinical factors. Methods: Clinical data of 282 patients who underwent SILA between January 2024 and January 2026 were retrospectively analyzed, comprising 93 patients in the normal weight group, 97 in the overweight group, and 92 in the obesity group. To control for baseline confounding, a 1:1 nearest-neighbor PSM with a strict caliper of 0.02 was performed based on preoperative covariates, including age, gender, comorbidities, history of abdominal surgery, preoperative delay, and pathological diagnosis. Intraoperative parameters and postoperative recovery profiles were subsequently compared among the matched groups. Results: After 1:1 propensity score matching, a well-balanced cohort was successfully analyzed, with all preoperative baseline variables closely aligned (all Conclusion: While single-incision laparoscopic appendectomy remains safe and technically feasible, an elevated BMI was associated with impaired operative efficiency, more intense early postoperative pain, and slower short-term gastrointestinal recovery. Clinicians should fully weigh these hidden recovery costs and metabolic stress profiles during perioperative management for overweight and obese patients.
