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
The effect of statins on progression of coronary artery calcium (CAC) density as measured by noncontrast computed tomography (CT) remains unknown. We examined the association of statin therapy with temporal changes in compositional calcium density using quantitative assessment of CAC scoring CT. This was a retrospective, single-center study of asymptomatic individuals undergoing serial CAC scoring CT. Scans were analyzed using a fully automated deep learning model, with quantification of total CAC volume and volumes of calcium compositional subtypes stratified by Hounsfield unit (HU) density: 130-199; 200-299; 300-399; ≥400 HU. Of 316 patients (58.4 ± 10.1 years; 49.1% male) with CAC present at baseline and rescanned at a mean interval of 3.8 ± 1.7 years, 175 (55.4%) patients were statin-treated and 141 (44.6%) patients were statin-naive. In patients exhibiting only low-density calcium (130-199 HU) at baseline, statin therapy was associated with a temporal decrease in CAC volume (β - 0.05[-0.09 to - 0.02]; p < 0.05). Among patients with ≥ 2 calcium compositional subtypes at baseline, statin therapy was associated with a greater temporal increase in volumes of each density stratum (130-199 HU: β 0.05[0.00-0.11]; 200-299 HU: β 0.11[0.07-0.14]; 300-399 HU: β 0.11[0.07-0.16]; ≥400 HU: β 0.11[0.06-0.16]; all p < 0.05). Similar results were observed for changes in relative proportions of each density stratum (all p < 0.001). In asymptomatic individuals undergoing serial CAC scoring CT, statin therapy was associated with a shift toward denser calcium, considered a more stable phenotype. Assessment of CAC density may capture more unique aspects of plaque progression and stability beyond traditional CAC scoring.
