Comparison of surgical approaches for pectus excavatum in children and adolescents: a single-center retrospective study.

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 compare the clinical utility of two modified Nuss procedures in children and adolescents with pectus excavatum (PE), including single-incision modified Nuss and modified Nuss with non-flipping bar. It sought to delineate patient selection patterns, assess perioperative parameters, postoperative recovery, complication rates, and short/intermediate-term efficacy of the two approaches, thereby providing evidence-based guidance for individualized surgical selection. Methods: A single-center retrospective cohort study was conducted on pediatric and adolescent PE patients who underwent surgical correction at Shanghai Children's Hospital between January 2015 and December 2022. Patients were categorized by the intended operative strategy: single-incision modified Nuss (single working incision with optional thoracoscopy through the same incision) versus modified Nuss with a pre-shaped non-flipping bar (advanced without intraoperative 180° turnover). A total of 171 patients were included (140 single-incision; 31 non-flipping bar). Demographic data, clinical characteristics, surgical parameters, and postoperative outcomes were collected. Results: Regarding surgical parameters, the non-flipping bar group had longer median operative time, more incisions, and lower screw fixation rate. Postoperatively, the non-flipping bar group showed a higher median Haller index, but this difference had limited clinical significance. No significant differences were noted in overall complication rates, postoperative recovery indicators, or surgical efficacy. After PSM, no statistical difference in therapeutic efficacy was found between the two groups. Conclusion: Both the single-incision modified Nuss procedure and the modified Nuss procedure with non-flipping bar are effective and safe for PE in children and adolescents, with comparable therapeutic efficacy. Surgical selection should be tailored to patient age and deformity characteristics.
