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
Background: Prolonged antiplatelet-agent administration associated with stenting for acute myocardial infarction is not ideal in young patients. We successfully performed a perfusion balloon-based kissing balloon technique in the left anterior descending artery ostium in a young patient with acute myocardial infarction. Case summary: A 34-year-old female presenting with recurrent chest pain was diagnosed with ST-segment elevation acute myocardial infarction. Emergency coronary angiography revealed 90% stenosis of the left anterior descending artery ostium. Considering her age, lesion dilation using a perfusion balloon was preferred. This inadvertently impinged the left circumflex artery, causing chest pain and ischaemia-related hypotension with only a 10 s perfusion dilation balloon. We transitioned to an alternative 7 Fr guiding catheter and performed the kissing balloon technique using a perfusion balloon. This allowed prolonged inflation for 120 s, without complications. Optical coherence tomography of the lesion revealed layered plaques. Based on the patient's age and medical history, coronary spasm may be the aetiological factor underlying acute ST-segment elevation myocardial infarction. Coronary angiography 3 months post-discharge revealed no restenosis. Discussion: Regarding acute myocardial infarction, prolonged inflation with a perfusion balloon had higher frequency of non-stent-related interventions than that of semi-compliant or non-compliant balloons. In this case, the perfusion balloon resulted in chest pain and hypotension. Perfusion balloon-based kissing balloon technique was useful in this setting. Optical coherence tomography revealing the responsible lesions can help determine the cause of acute myocardial infarction in young patients; in our case, a layered plaque was observed. Layered plaques are associated with coronary spasm; therefore, initiating treatment of coronary spasm was considered herein.
