Coronary artery changes in congenital coronary-cameral fistulas evaluated by computed tomographic angiography.
Article in Japanese journal of radiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 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
purposeThe study sought to determine coronary artery diameter in congenital coronary-cameral fistula (cCCF), factors associated with coronary artery aneurysm, coronary artery changes after fistula closure, and computed tomographic (CT) findings after treatment. MATERIALS AND
methodsWe retrospectively reviewed CT findings of the cCCF for origins, terminations, fistula length, complexities, and Sakakibara classification. Coronary artery diameter was expressed as coronary artery Z score. Fistula features associated with coronary artery aneurysm were analyzed. Post-fistula closures were analyzed for coronary artery dilatation, coronary thrombosis, complete fistula closure, and fistula thrombosis.
resultsTwenty-five patients (median age 33 months, interquartile range, IQR 25-48) were included. Coronary feeders and terminations were frequently right coronary artery (48%) and right ventricle (56%), respectively. Fistula aneurysm occurred in 52% of cases. Mean coronary artery Z score was 13.03 ± 6.36 with a high incidence of giant coronary artery aneurysm (68%). We found no statistically significant risk factors associated with coronary artery aneurysm (p value range 0.075-0.370). Median duration of the follow-up CT after closure of the fistulas was 6.4 months (IQR 5.0-8.7). Coronary artery Z score significantly decreased by 0.82 (IQR 0.28-1.35), p = 0.006 and coronary thrombosis occurred in 23% of cases during follow-up.
conclusionsLarge coronary aneurysm is common in cCCF. No characteristic feature of the fistula influencing coronary artery aneurysm is identified. There is a diminution in coronary artery Z score after fistula closure. Coronary thrombosis is a major complication after treatment.
