BMI and mortality in critically ill patients with COVID‐19: another brick in the wall of the obesity paradox
Authors' conclusion
Obesity was not associated with higher mortality rates in critically ill patients with COVID-19. Moreover, patients with BMI < 25 kg/m2 had a higher mortality rate compared with those in higher BMI categories.
