In the analysis of cytokines related to the inflammatory response, the comparison between groups using more detailed radiologic findings focused on pulmonary fibrosis (fibrotic findings vs. fibrotic-like findings vs. others) revealed significantly higher levels of convalescent IL-6 in patients with fibrotic findings than in those with fibrotic-like findings and others (Fig 2). The gene discussed is IL6; the disease is pulmonary fibrosis.
