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
purposeThis study aimed to assess perioperative features, early postoperative outcomes, and mid-term cardiac function in children with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) undergoing surgical repair.
methodsA retrospective review of 23 patients treated surgically between 2007 and 2023 was conducted. Patients were categorized into infants (<1 year) and older patients (>1 year). Clinical, operative, and echocardiographic data were analyzed, including left ventricular ejection fraction (LVEF) and mitral regurgitation (MR). Follow-up evaluations were performed at 1 and 6 months postoperatively.
resultsThe median age at surgery was 9 months. Early mortality occurred in 17.4%, with no late deaths during follow-up. Preoperative LVEF was significantly lower in infants than in older patients (p = 0.013). Among 19 survivors, LVEF improved markedly by 1 month and normalized in all patients by 6 months. MR was present in 89.5% preoperatively, with 47.3% showing moderate to severe grades. At 6 months, MR improved in most cases, with only 2 patients exhibiting residual moderate regurgitation and no severe cases.
conclusionsALCAPA is a rare but surgically correctable condition. Early surgical intervention leads to significant recovery of ventricular function and regression of MR within the first 6 postoperative months.
