Detection of Anatomical Variations and Pathological Findings of Coronary Arteries Using CT Coronary Angiography (CTCA) in Sudanese Adults in a Tertiary Hospital.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIschemic heart disease (IHD) is a leading cause of morbidity and mortality worldwide. Traditional diagnostic methods relied on electrocardiography (ECG) and cardiac enzyme testing, with limited accuracy. With advances in imaging, ECG-gated CT coronary angiography (CTCA) has become a reliable, non-invasive tool for risk assessment and diagnosis of coronary artery disease (CAD).
methodsA retrospective, cross-sectional study was conducted in the radiology department of Ahmed Gasim Hospital, Sudan. Data were extracted from 95 CTCA reports between January 2020 and June 2022 using a structured 14-item questionnaire. Patient demographics, calcium scores, coronary stenosis/occlusion, congenital anomalies, and anatomical variations were analysed.
resultsThe mean patient age was 51 years (range: 20-87), with male patients comprising 56.8%. Most patients (63.2%) had a calcium score of zero. Among positive scores, 17.9% were <100, 13.7% were 100-500, 2.1% were 500-1000, and 3.2% were >1000. The left anterior descending artery (LAD) was the most frequently affected artery (20.0%), followed by the right coronary artery (RCA) (13.7%), and left circumflex artery (LCX) (10.5%); left main coronary artery (LMCA) showed no stenosis. Proximal severe stenosis was the predominant pattern. Congenital anomalies were detected in six patients (6.3%), most commonly myocardial bridging. Anatomical variations were also found in five patients (5.3%), with malignant RCA origin from the left cusp being the most frequent.
conclusionCTCA effectively identified calcium scores, stenosis, congenital anomalies, and anatomical variations in Sudanese patients. Findings highlight a predominance of proximal severe stenosis in LAD and RCA, with myocardial bridging as the most frequent congenital anomaly and malignant RCA origin as the most common variation.
