Conclusion
In conclusion, we found that atorvastatin therapy has positive effects
on the course of hospitalization in patients with severe COVID-19.
Mostly these effects were seen in important outcomes of these patients
i.e., mortality rate, duration of hospitalization, and needs for
mechanical ventilation due to COVID-19. Prospective randomized
controlled trials are to be recommended to confirm the effect of statins
on patients with viral infections, especially severe COVID-19.
