Integrating Invasive and Noninvasive Imaging for Coronary Atherosclerosis: A Systematic Review With Pragmatic Algorithms From Anatomy to Physiology.
Review in Cureus, 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
Accurate detection and characterization of coronary atherosclerosis are essential for risk stratification and for guiding revascularization strategies. We aim to provide a pragmatic comparison of invasive and noninvasive imaging approaches for the detection, physiological assessment, and clinical management of coronary atherosclerosis. This review compares invasive techniques-coronary angiography, wire-based physiological assessment using fractional flow reserve (FFR) and instantaneous wave-free ratio, and intravascular imaging with intravascular ultrasound and optical coherence tomography - with noninvasive strategies including coronary artery calcium scoring, coronary computed tomography angiography (CCTA) with or without computed tomography - derived FFR, stress echocardiography, single-photon emission computed tomography, positron emission tomography (PET) with absolute myocardial blood flow quantification, and stress cardiovascular magnetic resonance imaging. We summarize diagnostic performance for anatomical plaque detection and ischemia assessment, strengths and limitations, patient selection considerations, safety issues related to radiation and contrast exposure, and downstream clinical impact. Invasive modalities remain the reference standard for lesion-level anatomical and physiological assessment when revascularization is contemplated. In contrast, noninvasive tests efficiently triage symptomatic patients, characterize plaque, and quantify ischemia and microvascular dysfunction. A pragmatic diagnostic algorithm integrates non-invasive anatomical or physiological testing as the initial step. It reserves invasive evaluation for high-risk findings or when percutaneous coronary intervention or coronary artery bypass grafting is likely. Future directions include refined plaque characterization on CCTA, quantitative PET perfusion imaging, computed tomography-derived FFR, and artificial intelligence-assisted image analysis.
