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
backgroundThe study aimed to investigate the correlation of carotid plaque and peripheral carotid adipose tissue (PCAT) characteristics with coronary computed tomography-derived fractional flow reserve (CT-FFR) values.
methodsData of 136 patients who underwent head and neck computed tomography angiography (CTA) followed by coronary CTA were retrospectively reviewed. Based on their CT-FFR values, they were divided into CT-FFR ≤ 0.8 and CT-FFR > 0.8 groups. The patients' baseline data, carotid plaque and PCAT characteristics were collected. Univariate analysis and multivariate logistic regression were employed to identify differences between groups.
resultsUnivariate analysis indicated a statistical differences in carotid plaque thickness, plaque area, plaque load, the carotid plaque Crouse score, minimum plaque density, and net enhancement value of PCAT of patients (P < 0.05). Based on this, multivariate logistic regression analysis demonstrated that carotid plaque thickness (odds ratio (OR) = 0.553; 95% confidence interval (CI) = 0.360-0.847), the carotid plaque Crouse score (OR = 0.653; 95% CI = 0.514-0.830), and net enhancement value of PCAT (OR = 0.820; 95% CI = 0.730-0.919) were independent predictors of the diagnosis of CT-FFR ≤ 0.8. Furthermore, receiver operating characteristic curve analysis showed that the area under the curve of plaque thickness, the carotid plaque Crouse score, and net enhancement value of PCAT for the diagnosis of CT-FFR ≤ 0.8 were 0.816, 0.843, and 0.836, respectively.
conclusionCarotid plaque thickness, the carotid plaque Crouse score, and net enhancement value of PCAT are independent related indicators of CT-FFR ≤ 0.8, which can be simultaneously clarified by head and neck CTA alone, as well as the severity of coronary atherosclerosis.
