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
backgroundLimited-access surgical repair remains important for adults with large atrial septal defects (ASDs) when transcatheter closure is unsuitable. This research aimed to compare early outcomes of inferior mini-sternotomy and right axillary vertical mini-incision for large ASD repair under cardiopulmonary bypass (CPB) without aortic cross-clamping.
methodsThis retrospective study included 79 adults from January 2020 to January 2024. Based on surgical approaches, patients were divided into Group A (n = 40, inferior mini-sternotomy) and Group B (n = 39, right axillary vertical mini-incision). Operative variables, postoperative recovery, pain scores, complications, costs, and 3-month follow-up findings were compared.
resultsAll patients underwent successful repair without perioperative death, conversion, reoperation, major residual shunt, stroke, or low-output syndrome. Operative time, CPB duration, transfusion volume, duration of tracheal intubation, ICU stay, postoperative hospital stay, hospitalization cost, and myocardial injury markers were comparable between groups. Group B had higher pain scores on postoperative days 2 and 3 (P < 0.05). Pulmonary infection, pneumothorax, pleural effusion, and phrenic nerve palsy occurred only in Group B, whereas superficial wound infection, sternal malunion, and hypertrophic scar or keloid occurred only in Group A; most complication differences were not statistically significant. During 3-month follow-up, no death, reoperation, major residual shunt, cerebrovascular event, or severe rhythm-related event was observed.
conclusionsBoth approaches enabled safe early large ASD repair on-pump CPB without aortic cross-clamping. Right axillary vertical mini-incision offered better scar concealment but greater early pain and pulmonary-management demands.
