CDH5 and COVID-19: However, t-test analysis showed higher levels of VE-cadherin (CD144) in the moderate COVID-19 patients’ Evs compared to HC Evs (15.38 ± 7.189 vs. 7.928 ± 5.314, p = 0.0221) and large size effects (Cohen’s d > 0.9) in CD144 EV expression were seen between HCs and the severe patient subgroups (Figure 3a).
