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
objectivesAnomalous left coronary artery from the pulmonary artery (ALCAPA) syndrome is a rare congenital coronary artery malformation with a high rate of clinical missed diagnosis and misdiagnosis. At present, there is a lack of reports on the clinical manifestations of ALCAPA and the imaging features of coronary computed tomography angiography (CTA). This study aims to summarize the clinical characteristics and coronary CTA imaging features of ALCAPA to improve the clinical diagnosis and treatment.
methodsThe clinical data of 24 ALCAPA syndrome patients were retrospectively collected, analyzed and summarized from January 1, 2013 to February 1, 2023 in the Second Xiangya Hospital of Central South University. According to the left and right coronary collateral circulation, the patients were classified into infantile type (7 cases) and adult type (17 cases). The differences of clinical manifestations and CTA imaging features were compared between the 2 types of patients.
resultsOf the 24 patients, a male-to-female ratio was at 1꞉5, and the median age of onset was 3.22 months for the infant type and 22.0 years for the adult type. The infantile type showed symptoms of left heart insufficiency at an early stage, while the adult type had a variety of clinical manifestations in 7 patients being asymptomatic and presented with a cardiac murmur on physical examination, 6 with symptoms of chronic myocardial ischemia, and 2 with malignant arrhythmias. CTA showed that 11 patients' the left coronary artery originated from the left posterior sinus of the pulmonary artery. All 7 infantile type patients had an enlarged left heart, left ventricular hypertrophy, reduced left heart function, lack of collateral circulation between the left and right coronary arteries, and normal coronary artery diameter. All 17 adult type patients showed dilated and tortuous coronary arteries with rich collateral circulation, and 7 adult type patients had preserved left heart function.
conclusionsThe clinical manifestations and CTA imaging features of patients with the 2 types of ALCAPA are different, while CTA performance is characteristic and can be used as a means of definitive diagnosis, staging, surgical evaluation, and postoperative follow-up of ALCAPA syndrome.
