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
backgroundMyocardial infarction (MI) with non-obstructive coronary arteries presenting with ST-segment elevation can be challenging. Understanding the cardiac and non-cardiac causes aid in identifying the underlying diagnosis and deciding on the management. Neurological insult resulting in a mismatch of oxygen supply or demand to cardiomyocytes can lead to type 2 MI. Acute brain injury, such as intracranial haemorrhage, can induce cardiac dysfunction secondary to brain-heart interaction via hypothalamic-pituitary-adrenal axis and catecholamine surge. CASE SUMMARY: A 50-year-old Caucasian male who vaped cannabis presented with epileptic seizures. A Glasgow coma scale of 7/15 necessitated urgent intubation. Electrocardiogram showed ST-segment elevation in inferior leads. Computed tomography of the head suggested intracerebral haemorrhage. He was stabilized in the intensive care unit (ICU). Subsequent imaging confirmed anterior communicating cerebral artery aneurysm and haematoma. Echocardiogram showed severe left ventricular dysfunction and hypokinesia in the left circumflex (LCx) territory. After step down from ICU, cardiac magnetic resonance imaging revealed transmural MI and myocardial oedema at LCx territory. Coronary angiogram was normal. Patient was treated with Levetiracetam and heart failure regimen. A cardiac defibrillator was implanted for secondary prevention and he was scheduled for elective neurosurgical intervention. A follow-up outpatient echocardiogram was normal. DISCUSSION: Myocardial infarction with non-obstructive coronary arteries is uncommon. Though the majority is due to either plaque disruption or myocarditis, non-cardiac causes, such as acute neurological insults and substance use, should be considered. Scrutinizing the clinical presentation and using a meticulous approach with appropriate investigations are required to reach the correct diagnosis and appropriate management.
