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
backgroundCarotid and coronary atherosclerosis are critical determinants of cardiovascular risk, yet their interrelationship in middle-aged populations is incompletely understood. This study assessed carotid plaque composition, risk-factor associations, coronary disease, and sex differences in a subclinical cohort.
methodsWithin the Swedish CArdioPulmonary bioImage Study, 533 asymptomatic individuals aged 50-64 years with carotid plaque ≥2.7 mm on ultrasound underwent 3T multi-contrast carotid cardiovascular magnetic resonance (CMR) and coronary computed tomography angiography. Carotid plaque characteristics were determined manually using established criteria on multi-contrast weighted carotid CMR. Bayesian regression models evaluated associations between cardiovascular risk factors and coronary atherosclerosis.
resultsLipid-rich necrotic core (LRNC) was present in 60% (320/533) and intraplaque hemorrhage (IPH) in 5.4% (29/533); calcification occurred in 48.6% (259/533). Maximum carotid wall thickness was 1.8 (1.6-2.0) mm, and mean lumen area 31.3 (26.7-36.1) mm². Coronary atherosclerosis was present in 63.6% (339/533) of participants, with ≥50% stenosis in 12.9% (69/533), and coronary artery calcium score >400 in 12.8% (68/533). Men (N = 367) had larger carotid lumen area, mean wall area, and maximum wall thickness (all p < 0.001) than women (N = 166), differences that persisted after body-surface-area adjustment (all p < 0.01). LRNC was present in 66% (242/367) of men compared to 47% (78/166) of women (p < 0.001). LRNC presence was not associated with coronary atherosclerosis, whereas IPH was associated with coronary involvement.
conclusionIn middle-aged individuals, distinct cardiovascular risk factors were positively linked to the presence and volume of LRNC and calcified plaques. The substantial prevalence of high-risk plaque features, particularly LRNC and especially in men, highlights a significant subclinical carotid disease burden.
