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
backgroundSurgical closure of atrial septal defect (ASD) is contraindicated in the condition with severe pulmonary arterial hypertension (PAH), whereas ASD closure in an effective intervention to normalize the structure and function of the right heart after previously experiencing volume overload due to shunting from the defect. This study aimed to evaluate normalization of the right heart and emergence of PAH after surgical closure of ASD.
methodsThis retrospective study was carried out in 45 patients over 18 years who had undergone surgical closure of ASD. The study has the aim to evaluate the morphological and functional parameters before and after the surgical approach and the preoperative factors that influenced the development of pulmonary arterial hypertension (PAP) after the ASD closure.
resultsThe majority of subjects were female (73.3%) although there were no significant differences between males and females from the various parameters. The average of mPAP in the group that experienced PAH was higher than non-PAH group after ASD closure (p = 0.019, 31.23 ± 12.70 mmHg vs 24.07 ± 13.08 mmHg). Significant differences were found in the Right Atrium (RA) dimension, Right Ventricle (RV) dimension, Tricuspid Regurgitation Velocity (TRV) and Tricuspid Annular Plane Systolic Excursion (TAPSE) between before and at 6 months after ASD closure (p = 0.000, p = 0.000, p = 0.000, p = 000, respectively). The sensitivity of the predictive model to estimate PAH at 6 months after surgical closure of ASD was 58%, with a specificity of 62.5%.
conclusionStructural and functional normalization of the right heart occurs at 6 months after surgical closure of ASD with the decrease of RA and RV dimensions and improvement from tricuspid regurgitation. Emergence of PAH after ASD closure was influenced by higher mPAP before surgical approach.
