Problem:
Researchers investigated the long term impact of non-alcoholic fatty liver disease (NAFLD) in terms of mortality utilizing data from the National Health and Nutrition Examination Survey (1988-1994). They compared mortality rates (median 14.5 year follow-up) among those with advanced fibrosis to those without fibrosis. They reported HR=1.69 (95% CI 1.09-2.63). What does this result indicate about the risk of mortality for NAFLD patients with advanced fibrosis compared to NAFLD patients without fibrosis? Group of answer choices Those with advanced fibrosis have a greater risk of mortality within 14.5 years than those without fibrosis. There is no difference in risk of mortality within 14.5 years between those with advanced fibrosis and those without fibrosis. There is a greater risk of mortality within 14.5 years for those without fibrosis compared to those with advanced fibrosis.
