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 conventional surgical treatment for postinfarction left ventricular aneurysm (LVA) is open-heart repair with cardiopulmonary bypass. However, the risk of the open-heart surgery under cardiopulmonary bypass may result in an unacceptable risk for many patients with multiple comorbidities. Here, we reported a new off-pump repair technique for postinfarction apical LVA.
methodsA new off-pump repair technique, circular banding and occlusion technique, was applied to repair the postinfarction apical LVA in 12 patients. Clinical data of all those 12 patients were retrospectively reviewed. Patients were followed up prospectively by direct interviews and echocardiographic examination.
resultsThe new repair technique was successfully performed in all these 12 patients. Acute reduction of the LVA mouth diameter, the left ventricular (LV) end-diastolic volume and end-systolic volume, and an increase in the LV ejection fraction (EF) were immediately obtained after the repair. Patients had an uneventful postoperative course. They were in New York Heart Association class 1-2, and the LV volume and EF detected by echocardiography remained unchanged during an average 28.4 ± 9.9 months (range 13 to 45 months) follow-up.
conclusionsCircular banding and occlusion is a simple, safe, and effective off-pump repair technique for postinfarction apical LVA. It can allow effective LV remodeling and improve heart function.
