Unexpected Findings in Diffuse ST-Segment Depression and aVR ST-Segment Elevation.

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
Electrocardiographic changes resembling myocardial ischemia are rare in gastrointestinal emergencies. In particular, gastric perforation has been reported in association with ST-segment elevation, but not with ST-segment depression mimicking non-ST-segment elevation myocardial infarction (NSTEMI). We report the case of a 60-year-old woman presenting with sudden-onset epigastric pain radiating to the chest. She remained hemodynamically stable throughout her emergency department stay. On admission, the ECG showed diffuse ST-segment depression with ST-segment elevation in aVR. High-sensitivity troponin and inflammatory markers were within normal limits. Coronary angiography revealed no significant coronary stenosis, and left ventriculography demonstrated preserved left ventricular systolic function. Abdominal computed tomography showed abundant pneumoperitoneum, diffuse anterior gastric wall thickening, and moderate intraperitoneal fluid, findings highly suggestive of gastric perforation. The patient underwent laparoscopic gastric repair and abdominal lavage, with an uneventful postoperative recovery. A repeat ECG 24 h after surgery showed complete resolution of the ST-segment abnormalities. To our knowledge, this is the first reported case of gastric perforation presenting with diffuse ST-segment depression and aVR ST-segment elevation. Awareness of this presentation helps to broaden the spectrum of diagnostic possibilities and to plan appropriate diagnostic-therapeutic procedures.
