A Distinctive Electrocardiographic Pattern: Unveiling the Spiked Helmet Sign.
Article in JACC. Case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe spiked helmet sign (SHS) on electrocardiogram (ECG) is a rare and distinctive pattern of ST-segment elevation resembling a traditional spiked German military helmet. Counterintuitively, it is typically not associated with cardiac conditions. CASE SUMMARY: We report a case of gastric dilatation with this ECG phenomenon. DISCUSSION: SHS is an uncommon ST-segment elevation manifestation of gastric dilatation likely due to gastric distention-induced vagal stimulation affecting cardiac repolarization. ST-segment elevations in the ECGs of acutely ill patients can have different causes, eg, left bundle branch block, early repolarization, pericarditis, TakoTsubo cardiomyopathy, and gastric dilatation. Recognition of the underlying cause is crucial to accurate diagnosis and appropriate management. TAKE-HOME MESSAGES: ECG changes must be interpreted in the context of the patients' condition and other investigation results such as troponin, electrolytes, and imaging. ECG findings including SHS can be easily misinterpreted and prompt inappropriate management.
