First, the prevalence of fatty liver disease in the propensity-matched obese cohort was 5%. 2, 3 Patients with non-alcoholic fatty liver disease (NAFLD) may have an accelerated rate of progression to severe COVID-19. 4 Thus, estimating the true prevalence of NAFLD in such a large population, and evaluating its impact on the outcomes, would help in understanding the implications of COVID-19 in patients with obesity. The authors matched the two cohorts for multiple risk factors for mortality; however, the severity of COVID-19 at presentation, which is an important determinant of outcomes, was not matched.
