1 · What the graph read from it

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.

2 · The registry

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

backgroundElectrocardiographic localization of the infarct-related artery in ST-segment elevation myocardial infarction is generally reliable; however, coronary anatomical variants and dynamic ischemic processes may result in misleading initial ECG patterns. CASE PRESENTATION: We describe a clinical scenario in which isolated inferior ST-segment elevation was the initial ECG manifestation of acute myocardial infarction, while coronary angiography revealed complete occlusion of the proximal left anterior descending artery. Subsequent angiography demonstrated a wrapped left anterior descending artery extending beyond the apex and supplying the inferior wall. Serial electrocardiograms showed a sequential evolution, with resolution of inferior ST-segment elevation after reperfusion followed by the emergence of anterior changes, rather than simultaneous multiterritory involvement.

conclusionAwareness of this dynamic ECG phenomenon is essential to avoid diagnostic delay in high-risk presentations.
