Effects of Gender on Electrocardiography in Subjects with Shortened Ventricular Depolarization (QRS).

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
backgroundDistinctions between electrocardiograms of female and male subjects have been recognized for many years. Due to these differences, arrhythmias in each gender have a tendency to differ. In our study, we aimed to compare electrocardiography intervals between men and women with short QRS durations.
methodsSubjects with a QRS interval of ≤80 ms were included in the study. Patients were grouped by gender and the parameters were compared. Patients with diseases that might affect QRS interval and/or who were on medications were excluded. The electrocardiogram intervals of the subjects were measured, Holter monitors were placed, and parameters of time-based heart rate variation were analyzed.
resultsA total of 100 patients (55% female) were included in the study. According to statistical analysis, no significant difference between the genders was observed in the heart rate or in the parameters, such as QT, JT, JTp, and TpTe intervals or heart rate-corrected QTc, JTc, JTpc, and TpTec intervals, which affect repolarization and are known to be arrhythmia precursors by shortening or elongation. No statistically significant difference was found between the two groups for the parameters of heart rate variability time measures (SDNN, SDANN, rMSSD, and pNN50).
conclusionWe observed that when the QRS interval gets shorter, repolarization differences between the genders disappear. New studies are required on this subject.
