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

Coronary artery aneurysm (CAA) is defined as a focal dilation that exceeds 1.5 times the diameter of adjacent normal coronary segments. Involvement of the left main coronary artery (LMCA), particularly when associated with a fistulous communication to the right atrium (RA), is exceedingly rare. We report a case of a 55-year-old male with a giant LMCA aneurysm and a coronary artery fistula (CAF) draining into the RA, diagnosed via coronary angiography and contrast-enhanced CT angiography. The patient underwent surgical closure of the LMCA-RA fistula. Following discharge, he developed worsening respiratory symptoms, and electrocardiography revealed atrial fibrillation, which later progressed to symptomatic bradycardia. Sick sinus syndrome was diagnosed, and a permanent pacemaker was successfully implanted. This case underscores the critical importance of early diagnosis and definitive surgical repair of LMCA aneurysms with fistulous connections, as well as the need for vigilant monitoring of potential postoperative complications such as arrhythmias, given the hemodynamic implications of left-to-right shunting and subsequent atrial stretch.
