1 · What the graph read from it

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.

2 · The registry

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

backgroundThe ECG abnormalities differences between Tibetans who were born and raised at high altitude and Han who had migrated to high altitude remain unrecognized in clinical practice. The aim of this study was to investigate the patterns and prevalence of ECG abnormalities in Tibetan natives from China, and to compare them to matched Han ethnicity individuals.

methodsThis study was a retrospective, comparative evaluation of the differences in ECG abnormalities between lifelong Tibetan natives and Han who had migrated to high altitude. ECG parameters (ventricular rate, PR interval, QRS duration, QT duration, and QTc), rhythm, voltage, and conduction were collected and compared.

resultsThe results of our study showed that ECG abnormalities consistent with right ventricular overload are less common in the Tibetan group than in the Han group. Additionally, participants in the Tibetan group reported a higher prevalence of early repolarization, atrial fibrillation, left ventricular hypertrophy, and left axis deviation than the Han group.

conclusionsThe findings in this study support and extend previous ECG observations in high-altitude residents. Future studies should clarify the clinical and prognostic significance of ECG abnormalities in high-altitude populations with different ethnic backgrounds.
