Evaluating the efficacy of right vertical infra-axillary thoracotomy vs. standard median sternotomy for atrial septal defect repairs: A single center analysis from Pakistan.

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: To compare early postoperative outcomes of Right Vertical Infra-Axillary Thoracotomy (RVIAT) versus Standard Median Sternotomy (SMS) for atrial septal defect (ASD) and partial atrioventricular septal defect (AVSD) repair. Methodology: A retrospective study was conducted from June 2024 to July 2025 at the Peshawar Institute of Cardiology. Patients were divided into SMS (n=36) and RVIAT (n=36) groups. Operative times, hematologic parameters, transfusion requirements, ventilation duration, drainage volume, ICU/hospital stay, and complications were analyzed. Multivariate regression was used to adjust for age differences. Results: The SMS group was significantly older than the RVIAT group (18.39 ± 11.65 vs. 6.80 ± 5.91 years; p<0.001). SMS showed longer cross-clamp time and higher ventilation time, chest drainage, and blood transfusion requirements. After adjusting for age, RVIAT retained lower blood transfusion volume, less chest drainage, and higher preoperative hemoglobin and platelet counts. ICU stay, hospital stay, and major complications were comparable between groups, with only one re-opening and two residual shunts in SMS. Conclusions: RVIAT is a safe, minimally invasive alternative to sternotomy, offering reduced postoperative morbidity and superior cosmetic outcomes. This is particularly advantageous for pediatric and young adult patients.
