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
introductionQT interval corrected dispersion (QTcd) reflects the heterogeneity of ventricular repolarization and has been proposed as a marker for arrhythmic risk in various neurologic and cardiac conditions. The aim of this study was to evaluate QTcd differences between children with epilepsy and healthy controls, with attention to age and antiepileptic drug use.
methodsA case-control study was conducted on 50 children with epilepsy and 50 age- and sex-matched control children admitted to Shahid Beheshti Hospital in Kashan in 2019. QTcd was manually measured from 12-lead electrocardiograms (ECGs). Data were analyzed using SPSS version 22.
resultsNo overall significant difference was observed in QTcd between groups (p > 0.05). However, children with epilepsy under 5 years of age had significantly higher QTcd than controls of the same age (p = 0.014). Moreover, QTcd was significantly lower in children with epilepsy receiving medication compared with those not on treatment (p = 0.026).
conclusionAlthough overall QTcd did not differ significantly between epileptic and control children, age under five and antiepileptic drug use significantly influenced QTcd. These findings suggest the importance of cardiac evaluation and early treatment in younger patients with epilepsy.
