Conclusion
The present study provides the first evidence for an association between enteral feeding with survival of ICU patients with COVID-19. According to the findings of the study, there was a significant inverse association between mortality and high-volume and high-protein formula. Prospective clinical trials and cohort studies should be performed to establish a causal relationship between enteral feeding and mortality and survival in ICU patients with COVID-19. If the results of the present study are confirmed in future research, it can be considered an effective strategy to reduce the mortality rate of these patients by recommending high-calorie and high-protein formulas to patients admitted to the ICU.
