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

Study objective: To establish sex-specific electrocardiographic (ECG) reference values in healthy Vietnamese late adolescents and characterize sex-based differences in repolarization patterns. Design: Cross-sectional observational study. Setting: University health screening program in Vietnam. Participants: A total of 5127 first-year university students (58.6 % female; age 17-29 years), all asymptomatic and without known cardiovascular or metabolic disease. Interventions: None. Main outcome measures: Standard ECG parameters (heart rate, PR interval, QRS duration, QTc, QRST angle), J-point elevation, ST-segment amplitude, and T-wave morphology in leads V1-V6, stratified by sex. Results: Significant sex differences were observed in all ECG parameters ( Conclusion: This is the first large-scale study to define sex-specific ECG reference values in a Vietnamese cohort. Marked differences in repolarization patterns emphasize the importance of ethnicity- and sex-specific criteria to enhance diagnostic accuracy and avoid misinterpretation in Southeast Asian populations.
