Protocol for optimizing the utilization rates of coronary angiography in Norway.
Article in Research in health services & regions, 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
backgroundInvasive coronary angiography (CAG) remains widely used in Norway, with 37% of procedures in 2022 yielding normal findings, indicating potential overuse.
methodsA national multidisciplinary task force performed a retrospective registry-based analysis and reviewed the European Society of Cardiology (ESC) guidelines to identify strategies aimed at reducing the utilization of CAG in patients with suspected coronary disease.
resultsSignificant regional variation in CAG and Coronary Computed Tomography Angiography (CCTA) utilization was observed. Complication rates for CAG in stable patients were low, 0.6%. In patients with low and moderate pre-test probability and suspected Chronic Coronary Syndrome (CCS), CCTA is recommended as a first-line imaging test.
conclusionStandardization of CCTA protocols and reports, using CAD-RADS 2.0, mandatory CCTA registration in Norwegian Registry of Invasive Cardiology (NORIC), and formal collaboration between radiologists and cardiologists are essential initiatives. The aim is to reduce invasive procedures not resulting in revascularization by 5-10 percentage points nationally.
