Figure 2.

Circulating levels of IL-6 in moderate and severe PC patients (A), as well as in moderate and severe PC patients with or without fibrosis-like symptoms (B) were reduced compared to healthy (black dots) and vaccinated (VAX, green dots) subjects. (A) Plasma levels of IL-6 were measured according to the grade of the disease (moderate or severe, pink and blue dots, respectively) and (B) to the establishment of lung fibrosis-like symptoms (moderate or severe PC patients with or without fibrosis, pink or blue dots and purple and bright blue dots, respectively). Data are expressed as median. Statistical analysis was performed according to the Mann–Whitney U test.
