Isolated First Septal Perforator Spontaneous Coronary Artery Dissection Causing Acute Myocardial Infarction.
Article in JACC. Case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIsolated spontaneous coronary artery dissection (SCAD) of the first septal perforator (S1) is rare. CASE SUMMARY: A 48-year-old man presented with chest pain after physical exertion. Coronary angiography demonstrated type 1 SCAD confined to S1. Cardiac magnetic resonance (CMR) confirmed a transmural septal infarction. The patient was managed conservatively with antiplatelet and beta-blocker therapy and experienced an uncomplicated recovery. DISCUSSION: A limited number of cases of isolated S1 SCAD have been previously reported, predominantly affecting women and all managed conservatively. To our knowledge, this case represents the youngest reported male patient and appears to be the first reported case demonstrating CMR-confirmed transmural septal infarction secondary to type 1 S1 SCAD. Optimal long-term medical therapy remains undefined. TAKE-HOME MESSAGES: SCAD should be considered in patients presenting with chest pain after physical or emotional stress. CMR is a valuable adjunct after angiography in cases of diagnostic uncertainty.
