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
backgroundWe investigated the role of ventricular repolarization parameters to predict complete atrioventricular block in patients undergoing transcatheter aortic valve implantation (TAVI).
methodsA total of 150 patients undergoing TAVI due to severe aortic stenosis were included in this retrospective cohort study. Patients were assigned in two groups based on the presence (n: 49) or absence (n: 101) of complete atrioventricular block after TAVI. Ventricular repolarization intervals (QT, QTc, JT, JTc, TP-E), indices (QT dispersion), and ratios (TP-E/QT, TP-E/QTc, TP-E/JTc) were measured.
resultsElectrocardiographic repolarization parameters such as Tp-e interval: 74.2 ± 5.1 versus 59.2 ± 6.1 ms, p < .001; QTc interval: 397.6 ± 3.4 versus 368.1 ± 7.8 ms, p < .001; JTc interval: 317.4 ± 11.3 versus 291.1 ± 6.7 ms, p < .001; Tp-e/QT ratio: 0.28 ± 0.04 versus 0.20 ± 0.04, p < .001; Tp-e/QTc ratio: 0.29 ± 0.04 versus 0.19 ± 0.03, p < .001; Tp-e/JT ratio: 0.32 ± 0.03 versus 0.23 ± 0.03, p < .001; Tp-e/JTc ratio: 0.30 ± 0.02 versus 0.2 ± 0.03, p < .001; and QT dispersion: 34.4 ± 3.0 versus 17.8 ± 3.6 ms, p < .01 were significantly higher in post-TAVI permanent pacemaker group. In a univariate regression analysis, pulmonary artery pressure, heart rate, coronary artery disease, Tp-e/QTc, Tp-e/JTc, and PR interval were significantly associated with complete heart block. Tp-e/JTc (OR 0.373, p = .067) and PR interval (OR 0.898, p = .079) were found to be independent predictors of these type of arrhythmias in a multivariate analysis. But it is not statistically significant.
conclusionOur results suggest that repolarization parameters may play a role in predicting complete atrioventricular block. Tp-e/JTc was found to be potential independent risk marker for this setting.
