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
Introduction: Total anomalous pulmonary venous drainage (TAPVD) constitutes approximately 1.5% of all congenital heart defects. Surgical correction has traditionally been performed using the conventional technique; however, the sutureless approach has emerged as a recent alternative. This study aims to compare the surgical outcomes of the two techniques and to identify the variables influencing them. Subjects and Methods: This was a retrospective study over a 17-year period from 2007 to 2024. There were 55 patients of TAPVD: supracardiac ( Results: The median age of surgical intervention was 43 days (interquartile range [IQR]: 30-120), and the median weight was 3.40 kg (IQR: 3.00-4.30). Prematurity was present in 3 (5.5%) patients, 11 (19.6%) had preoperative pulmonary vein obstruction, 2 (3.6%) had atrial septal defect obstruction, and 23 (41.1%) had preoperative pulmonary hypertension. Twelve (21.4%) patients required preoperative intubation, 4 (7.1%) required inhaled nitric oxide, and 7 (12.5%) had hemodynamic instability/cardiopulmonary resuscitation (CPR). Surgical correction (supracardiac and infracardiac) was by conventional repair in 20 patients and sutureless in 15 patients. When comparing sutureless and conventional TAPVD repair techniques, no statistically significant differences were observed in rates of pulmonary hypertension crisis, hospital stay duration, noninvasive ventilation duration, postoperative infections, or chest re-exploration rates. Similarly, the incidence of pulmonary venous obstruction (PVO) and early mortality was comparable between the two groups. The predictors of early mortality were seen in patients with preoperative pulmonary hypertension (odds ratio [OR]: 5.63, Conclusions: Early postoperative outcomes were found to be closely associated with the patients' preoperative clinical status. Overall, in our cohort, no difference was seen between the conventional and sutureless technique of TAPVD repair. These findings may be influenced by the study's limited sample size, potentially reducing its statistical power.
