Fibrinogen-to-albumin ratio as a novel biomarker in pneumoconiosis: a retrospective cohort study

Fibrinogen-to-albumin ratio was independently associated with pneumoconiosis, whereas albumin, fibrinogen, and blood lead did not retain significance after adjustment. Given its moderate discriminative ability, FAR should be considered a supportive and complementary biomarker reflecting systemic inflammation rather than a stand-alone diagnostic tool. Larger multicenter prospective studies are warranted to validate these findings. Int J Occup Med Environ Health. 2026;39(1):28-38.
