Correlation Between Fragmented QRS and Ventricular Function from Cardiac Magnetic Resonance in Patients with Repaired Tetralogy of Fallot.
Article in Pediatric cardiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Fragmented QRS is an abnormal sign in an ECG resulting from ventricular dyssynchrony. The presence of fragmented QRS (fQRS) is related to mortality in patients with repaired tetralogy of Fallot (rTOF). This study aimed to analyze the correlations between fQRS and ventricular function parameters from cardiac magnetic resonance (CMR) images. A total of 54 patients with rTOF or repaired DORV, TOF type who had been investigated by CMR at Songklanagarind Hospital from January 2012 to August 2019 were retrospectively reviewed. Most of the patients (47 patients, 87%) were diagnosed with TOF and most of these (57.4%) were treated with a transannular patch (TAP) on the right ventricular outflow tract (RVOT). Forty-four patients (81%) had fQRS. The median time interval between EKG and CMR was 4.2 months (IQR 1.1, 6.9). Patients with fQRS had significantly higher RVEDVi (145.6 [IQR 121.1, 173.1) vs. 115.9 [IQR 96.2, 146.9] mL/m
