Junior doctors' interpretation of the electrocardiogram: a cross-sectional survey in South African hospitals.

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
Background: Despite the electrocardiogram (ECG) being a critical bedside diagnostic tool, evidence suggests suboptimal ECG interpretation competence among doctors worldwide. Limited research exists evaluating the ECG interpretation skills of South African junior doctors. This study addresses an important knowledge gap in the literature which assesses the knowledge of "must-know" ECG conditions of junior South African doctors, previously identified through a Delphi study. Methods: This cross-sectional survey assessed ECG interpretation competence among 117 junior doctors across four public hospitals in Gauteng Province, South Africa. Data were collected over the period December 2024 to November 2025. Respondents completed a 20-question assessment based on consensus-derived "must-know" ECG diagnoses for medical students adapted from Viljoen's Delphi study, which identified ECG teaching priorities for medical schools using expert consensus performance was analysed according to professional category, training background, and emergency medicine exposure. Results: Overall mean score was 10.3/20 (51.5%), with only 34.2% achieving the predefined pass standard of 75%. Community service doctors outperformed interns (57.1% vs 49.1-49.3%) though not significantly ( Conclusion: Junior doctors in Gauteng demonstrated ECG interpretation deficiencies for life-threatening conditions such as poly and monomorphic ventricular tachycardia, and second and third-degree heart blocks. The lowest-scoring ECGs were those with pericarditis and right ventricular hypertrophy. Despite these findings, this study suggests that formal ECG training improves ECG diagnostic performance which has significant implications for curriculum development.
