CT-positive patients had significantly higher C-reactive protein (173.4 vs. 64 mg/L, p = 0.002) and elevated D-dimer (2.96 vs. 1.54 µg/mL, p = 0.018) than CT-negative patients. Moreover, a significantly lower PaO2/FIO2 ratio was observed in brain CT-positive patients (116 vs. 161, p = 0.033) (see Electronic Supplementary Material, e-Table 1 and e-Fig. 1).
