CC-chemokine ligand 18, CXC motif chemokine 13 and osteopontin as biomarkers of silicosis and asbestosis: a prospective observational study.
Observational study in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSilicosis and asbestosis, distinct forms of pneumoconiosis, manifest progressive interstitial fibrosis due to exposure to silica dust or asbestos fibers. This study aimed to identify potential biomarkers for diagnosing silicosis and asbestosis, while also evaluating disease severity and prognosis. We undertook an prospective observational study involving patients with silicosis or asbestosis. The correlation between baseline CC-chemokine ligand 18 (CCL18), CXC motif chemokine 13 (CXCL13), osteopontin (OPN), periostin, and fibulin-3 and clinical variables was analyzed. Diagnostic sensitivity was evaluated using receiver operating characteristic curves, and correlations between baseline biomarker levels and disease severity were analyzed. Multivariable Cox regression assessed the baseline concentrations' strength in predicting all-cause mortality for silicosis and asbestosis. Of 231 silicosis and 163 asbestosis included in the study, 29 silicosis (12.6%) and 28 (17.2%) asbestosis died within the five years follow-up period. Elevated baseline concentrations of CCL18, CXCL13, and OPN were observed in 231 silicosis patients and 163 asbestosis patients compared to 118 HCs. Diagnostic accuracy for silicosis or asbestosis, in order, was CCL18, OPN, and CXCL13. Combining CCL18, OPN, and CXCL13 enhanced diagnostic accuracy. In silicosis patients, these concentrations were significantly associated with lung function values. However, these biomarkers were not the risk factor for all-cause mortality. CCL18, CXCL13, and OPN stand out as promising biomarkers for diagnosing silicosis and asbestosis. Meanwhile, CCL18, CXCL13, and OPN may be used for the evaluation of silicosis conditions.
