Liver fibrosis index as a novel prognostic factor in patients with pulmonary arterial hypertension.
Article in Heart and vessels, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 dysfunction is an important determinant of the prognosis of left heart failure patients. However, few studies have reported on cardiohepatic interactions in right heart failure patients, a condition that is an important prognostic factor in pulmonary arterial hypertension (PAH). This study aimed to evaluate the existence and extent of hepatic fibrosis and its contribution as a prognostic factor in PAH. This prospective study enrolled 60 consecutive patients with PAH in the International University of Health and Welfare Mita Hospital from June 2016 to December 2017. After the application of the exclusion criteria, 35 patients were assessed for hepatic fibrosis, using real-time tissue elastography, and for clinical deterioration. Sixteen healthy controls were also assessed for comparison. The liver fibrosis index (LFI) was significantly higher in PAH patients than in healthy controls (1.214 ± 0.047 vs. 0.911 ± 0.059, P < 0.001), suggesting that PAH patients exhibited mild liver fibrosis. However, patients with deterioration (vs. no deterioration) had significantly higher LFI values (1.507 ± 0.078 vs. 1.080 ± 0.034, P < 0.001), independent from other established liver function parameters. A receiver operating characteristic curve analysis identified that an LFI ≥ 1.275 indicated a significant probability of clinical deterioration (hazard ratio: 8.4 (95% CI 1.5-45.4, P = 0.012), independent from other known PAH prognostic factors. PAH patients may exhibit subclinical liver fibrosis associated with chronic right heart failure. The LFI can serve as both a non-invasive evaluation of liver fibrosis and a predictive marker for the deterioration of PAH patients.
