J o u r n a l P r e -p r o o f disease progression. Not only, NASH and NAFLD are important predictive factors for the outcomes in acute and chronic disease processes but also the obesity surgery and its complications [7] . We think that the authors had reached the correct conclusion indirectly, as obesity is the primary aetiology for the liver disease [NASH, NAFLED] and rarely considered as independent conditions. When they coexist, they do so because of obesity.

Several other studies have reported obesity as a significant factor for mortality in Covid-19 patients [8-10].This subject is more important in the current Covid-19 crisis knowing the pandemic of obesity. In addition to the known defective immune system in the obesity, the virulence of Covid-19 and the differences in the incidence of obesity across the world, it is not clear what is the magnitude /severity of liver disease could add to production of critical illness like severe pneumonia. We believe more powerful studies are needed to confirm why obesity is a risk factor for critical illness and or mortality in Covid-19. This will help to reduce mortality in this vulnerable group of patients.
