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
backgroundMechanical dispersion (MD), defined as the standard deviation of time to maximum myocardial shortening assessed by 2D speckle tracking echocardiographic strain imaging (2DS), has been recently proposed as a predictor for ventricular tachycardia or fibrillation (VT/VF) in patients with ischemic cardiomyopathy and long QT syndrome. However, the role of MD in patients with non-ischemic cardiomyopathy (NICM) has not yet been studied. METHODS AND
resultsIn 20 patients with NICM (mean age 62 ± 11 years, 75 % male, mean EF 32 ± 6 %, mean QRS duration 102 ± 14 ms), we measured longitudinal strain by 2DS in a 16-segment left ventricular model and calculated the MD. Patients were divided into two groups, defined by the presence or absence of documented VT/VF. In 11 patients (55 %), VT/VF was documented. The median time from VT/VF to echocardiographic examination was 26 (IQR 15-58) months. There were no significant differences in baseline characteristics between patients with and without index events. MD was significantly greater in patients with VT/VF as compared to those without arrhythmias (84 ± 31 ms vs. 53 ± 16 ms, p = 0.017). The analysis of the ROC curve (AUC 0.81, 95 % CI 0.63-1.00, p = 0.017) revealed that dispersion >50 ms is associated with twelve times higher risk of VT/VF in patients with NICM (OR 12.5, 95 % CI 1.1-143.4, p = 0.024).
conclusionsIn this small cohort of NICM patients, greater MD was associated with a higher incidence of VT/VF.
