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
backgroundSpontaneous coronary artery dissection (SCAD) is a frequent cause of acute coronary syndrome in young to middle-aged women with few or no traditional cardiovascular risk factors. Chest pain is the most frequently described presenting symptom, but syncope is extremely rare. Herein, we report on a 16-year-old girl who presented with an episode of syncope occurring during a race. Despite significantly elevated troponin level, the diagnosis of the left main coronary artery SCAD with cardiogenic shock was delayed. CASE SUMMARY: A 16-year-old girl presented with an episode of syncope. Myocardial injury markers were positive. Echocardiography showed a mildly reduced left ventricular ejection fraction (50%). Although initially stable, she later experienced recurrent chest pain accompanying precordial ST segment elevation with dynamic changes and developed cardiogenic shock, necessitating emergent revascularization. Coronary angiography demonstrated almost total occlusion at the ostium and proximal segment of the left main trunk coronary artery (LMT). Intravascular ultrasound confirmed a false lumen with prominent dissection in the LMT. Percutaneous coronary intervention assisted by intra-aortic balloon pump was conducted in the LMT. A 3.5 mm × 24 mm everolimus-eluting stent was deployed to the focal lesions of the LMT. A postprocedural electrocardiogram showed alleviation of the precordial ST-segment elevation. The diagnosis of SCAD was confirmed. Transthoracic echocardiography showed an improved left ventricular ejection fraction (57%). The patient was asymptomatic during the 24-mo. follow-up period.
conclusionSCAD should always be considered in the differential diagnosis of acute coronary syndrome presentations in low-risk patients, regardless of age.
