In the COVID-19 group, patients with ARDS (n: 34) did not show differences in demographic characteristics, sex distribution, PT, aPTT, or D-dimer values compared to those without ARDS (n: 54) (Table 3); however, an increased fibrinogen median value has been shown in COVID-19 patients with ARDS (Table 4). Here, F2 is linked to acute respiratory distress syndrome.
