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
Liver fibrosis scores, such as the fibrosis-4 index (FIB-4I), a representative index of liver fibrosis, have recently been linked to heart failure, coronary artery disease (CAD), and atrial fibrillation (AF). We investigated the association between FIB-4I and AF in patients who underwent coronary computed tomography angiography (CCTA). This study included 1525 patients clinically suspected of having CAD or about to undergo treatment for AF, such as catheter ablation. FIB-4I and the presence or absence of AF were the primary endpoints. FIB-4I was higher in the AF group than in the sinus rhythm group (1.93 ± 0.94 versus [vs.] 1.75 ± 1.03, p = 0.001). No significant difference was observed in the FIB-4I between the paroxysmal AF and persistent AF groups (1.93 ± 0.99 vs. 1.94 ± 0.78, p = 0.922). Furthermore, FIB-4I was higher in the hypertension (HTN) group than in the non-HTN group (1.84 ± 1.04 vs. 1.62 ± 0.91, p < 0.001). Low FIB-4I (≤1.29) was proven to be a contributing factor for the absence of AF in all patients (odds ratio [OR]: 0.55, 95% confidence interval [CI]: 0.39-0.78, p < 0.001) as well as the HTN and non-HTN (OR: 0.53, 95% CI: 0.37-0.78, p < 0.001 and OR: 0.39, 95% CI: 0.23-0.68, p < 0.001, respectively) groups. Thus, FIB-4I may serve as a diagnostic indicator of the absence of AF in patients undergoing CCTA. The liver fibrosis-4 index as a diagnostic indicator of the absence of atrial fibrillation in patients undergoing coronary computed tomography angiography.
