Prevalence of Coronary Artery Calcification in Non-Contrast Non ECG-Gated Chest CT Scan of Patients With Significant Stenosis in Conventional Angiography in Comparison to Patients Without Significant Stenosis: A Cross-Sectional Study.
Article in Health science reports, 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
Background and Aims: Coronary artery disease is a main cause of mortality in developed and developing countries. Early diagnosis and treatment are important to reduce the burden of the disease. Correlation between coronary artery calcification in non-contrast non-ECG gated chest CT scan and conventional angiographic findings could be a helpful guide for risk assessment and the need for angiographic evaluation in patients with coronary artery calcification in non-contrast chest CT scan applied for other reasons. Methods: A retrospective cross-sectional study was conducted in the cardiology department of Sina hospital and patients who underwent angiographic study between march 2020 and april 2021 with recent non-contrast non ECG-gated chest CT scan were selected. patients with coronary stent and history of CABG were excluded and angiographic findings, prevalence, diameter and pattern of coronary artery calcification in CT scan was studied in the selected patients. Results: The prevalence of calcification in patients with significant stenosis was 94% and was significantly higher than patients without significant stenosis with prevalence of 46% ( Conclusion: The presence and extent of CAC on non-contrast, non-ECG-gated chest CT scans are correlated with significant coronary artery stenosis on angiography. These findings suggest that CAC assessment on routine chest CT scans can be used as a criterion for risk stratification and determining the need for angiographic evaluation to rule out significant stenosis.
