Diagnostic and prognostic value of coronary artery calcium scoring and computed tomography angiography in coronary artery disease: a systematic review and meta-analysis.
Review in Polish journal of radiology, 2026. 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
Coronary artery disease (CAD) remains a leading cause of disability and death worldwide. Noninvasive tests are crucial to ensure early diagnosis and risk stratification. The coronary artery calcium scoring (CACS), a non-invasive measure obtained using non-contrast computed tomography, reflects the calcific plaque burden, and may provide important diagnostic and prognostic information. This study aimed to systematically review and meta-analyze the recent literature to ascertain the diagnostic and prognostic usefulness of CACS in patients with suspected or established CAD. A literature search was conducted in PubMed, Scopus, and Web of Science for studies published between 2008 and 2024. The studies were included if they evaluated the prognostic and diagnostic value of CACS, either alone or with computed tomography angiography (CTA). Data extraction was performed for pooled sensitivities and specificities, hazard ratios (HRs), and event-free survival. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) criteria were used to assess methodological quality. Fourteen high-quality studies with a total of more than 80,000 patients were meta-analyzed. Subjects with CAC ≥ 100 were at a significantly increased risk of developing major adverse cardiac events (HR 2.7; 95% confidence interval: 2.1-3.6). CACS is highly beneficial in diagnostic discrimination (pooled sensitivity 88%, specificity 77%) in those presenting with chest pain but no prior history of CAD. It is essential to emphasize that CAC score of zero correlates with the best prognosis and very low rates of clinical events across various populations, including patients with diabetes and asymptomatic individuals. The CACS fills a special niche as a very strong predictor and non-invasive marker in the diagnosis and prognosis of CAD. Combining calcium scoring with CTA benefits clinical decision-making, particularly for patients categorized as low to intermediate risk.
