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
objectiveTo observe the changes in electrocardiographic parameters in children with complete left bundle branch block (CLBBB) after the transcatheter closure of simple ventricular septal defect (VSD).
methodsA total of 21 children with CLBBB early after transcatheter closure of perimembranous VSD were recruited. Another 21 children without any type of arrhythmia after transcatheter closure of perimembranous VSD were enrolled as the control group. The sex, age, and the size of occluder were matched between the two groups. The changes in the following indices were compared between the two groups: left ventricular voltage, QT interval, corrected QT interval (QTc), QT dispersion (QTd), corrected QT dispersion (QTcd), JT dispersion (JTd), and corrected JT dispersion (JTcd) on the electrocardiogram before transcatheter closure and at 1, 3, 5, 30 days after transcatheter closure.
resultsLeft ventricular voltage and JTcd changed with operation time in the CLBBB and control groups (P<0.05). There were interaction effects between time and grouping in the changes in left ventricular voltage and QTd (P<0.05). There was a significant difference in JTcd between the CLBBB and control groups (P<0.05). There was also a significant difference in left ventricular voltage between the CLBBB and control groups at 3 and 5 days after the transcatheter closure (P<0.05).
conclusionsThere are significant differences in electrocardiographic left ventricular voltage and JTcd between VSD children with and without CLBBB early after transcatheter closure. JTcd might be useful in predicting the development of CLBBB early after transcatheter closure of VSD.
