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
Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiovascular anomaly that occurs in approximately 1 in 300,000 live births. This study aimed at identifying preoperative predictors of immediate postoperative outcomes. We conducted a retrospective, cross-sectional, single-center study and reviewed echocardiographic and hemodynamic data from all patients before and after surgical repair of ALCAPA at our center from January 2004 to February 2018. In all cases, the left coronary artery arose from the main pulmonary artery or a major branch. A total of 10 patients (age 1 month to 10 years, median 3 months) underwent ALCAPA surgical repair during the study period. No patients required a left ventricular assist device (LVAD) before surgery, but 4 patients (40%) received an LVAD after the surgery. The left ventricular ejection fraction (LVEF) improved in all patients following surgery. The utility of preoperative factors associated with pre- and post-procedure LVEF was investigated. LV dimension, as well as right coronary artery (RCA) and left coronary circumflex artery (LCX) Z scores were associated with a higher LVEF in the preoperative state. Patients with larger RCA, left ascending artery (LAD), and LCX Z scores also had a shorter duration of mechanical ventilation and ICU stay following surgery. Patients with a RCA Z score < 4 required implantation of an LVAD postoperatively. ALCAPA patients with larger RCA and LCX demonstrated a higher preoperative LVEF, while those with larger RCA, LAD, and LCX had superior postoperative hemodynamics and clinical outcomes.
