The effectiveness of relative dose response to retinol intake as an evaluation of vitamin A status of cirrhotic patients

Abstract

VAD was highly prevalent in cirrhotic patients. However, in those with low serum RL and negative RDR, factors other than inadequate vitamin A intake, such as impaired hepatic vitamin A mobilization and intestinal vitamin A malabsorption, which were not examined in the present study, could have influenced the negative results obtained by the RDR method.
