“…In some studies, no statistically significant improvements in clinical outcomes were observed [21,22,26,28,29,31,33,37,39,40,42,44,46,49,52,53]. In contrast, other studies showed benefits of CovCP in terms of disease progression [23,25,27], mitigation of hypoxia [30], World Health Organization (WHO) severity score [32], respiratory parameters [24,54], rate and time to clinical improvement [20,34], need for intubation [50], extubation rate [35], recovery time from critical illness [55], rate of MV and vasopressor support [51], rate of transfer to MV [41], and clinical status [38] in the overall study population or specific subgroups of patients with COVID-19.…”
