Fig. 2 — VEGF, IL-1β and IL-10 concentration in control and post COVID-19 FF determined by ELISA. IL-1β (A) and VEGF(B) concentrations were decreased in FF from post COVID-19 compared with that in FF from control patients (VEGF: *p < 0.05, IL-1β: ****p < 0.0001). No differences were found between groups in terms of IL-10 levels (C) (p = 0.4).
