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
Pectus excavatum correction in adults is often pursued for functional and aesthetic reasons, yet modified Nuss and Ravitch procedures may be invasive and can leave residual anterior chest wall contour deformities. We report a single-center retrospective consecutive case series of aesthetic chest wall correction using patient-specific silicone implants designed with computed tomography (CT)-based three-dimensional (3D) computer-aided design (CAD), with descriptive assessment of postoperative patient-reported and morphological outcomes. Between 2018 and 2024, seven adults underwent CAD-assisted correction at a tertiary referral center (mean age 31.3 ± 11.0 years). Five had previously undergone modified Nuss or Ravitch repair. The primary outcome was postoperative chest-appearance satisfaction, assessed using a six-item questionnaire derived from the modified Nuss questionnaire and scored on a 5-point Likert scale. A mean overall satisfaction score (range 1-5) was calculated. As a secondary outcome, postoperative chest wall morphology was documented using upright 3D surface models (VECTRA WB360) for qualitative illustrative assessment of contour correction. At a mean follow-up of 3.2 ± 1.9 years, patient-reported outcome data were available for five patients and postoperative 3D surface models for four. Mean overall satisfaction was 3.3 ± 0.8 (range 2.3-4.1), with higher satisfaction for chest appearance when clothed than unclothed (4.0 ± 1.0 vs 2.8 ± 1.48). Qualitative 3D assessment suggested restoration of sternal projection and improved chest wall symmetry in all imaged patients. One patient developed postoperative seroma followed by infected hematoma requiring implant explantation. In this retrospective case series, available follow-up data suggested qualitative contour improvement and generally favorable patient-reported satisfaction, but also a non-negligible complication risk. Findings should be interpreted cautiously given the small sample, incomplete follow-up, and descriptive design.
