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

backgroundLeft main coronary artery (LMCA) aneurysms are exceedingly rare and most commonly associated with coronary artery disease. CASE SUMMARY: We report the case of a 70-year-old man with frequent runs of nonsustained ventricular tachycardia who was found to have a distal LMCA aneurysm without significant coronary artery disease. He was managed medically because of complex anatomy and minimal symptom burden. DISCUSSION: LMCA aneurysms are typically discovered incidentally during ischemic evaluation in association with hemodynamically significant coronary artery disease with reports often noting concomitant critical stenoses. Management in this case was complicated by involvement of the left main trifurcation. This patient's autoimmune neuromuscular disease and glucocorticoid exposure may have contributed to aneurysm formation. TAKE-HOME MESSAGES: Symptom burden is an important consideration in management decisions even in cases of giant LMCA aneurysms particularly if they are located distally. Blood pressure and heart rate regulation as well as serial imaging may be appropriate in certain cases.
