Impact of Pretransplant Hepatic Encephalopathy on Liver Posttransplantation Outcomes

Figure 2

Posttransplant cognitive function (𝑇 values) in patients with or without risk factors that were determined to be associated with cognitive impairment (i.e., cirrhosis of alcoholic etiology, diabetes mellitus, and prior HE). 𝑇 values were calculated using the following formula: 𝑇=50+10 ([raw test value − mean test value]/SD of normal population). Impairment was defined as 𝑇≤40. HE, hepatic encephalopathy; SD, standard deviation. Adapted with permission from Garcia-Martinez et al., Copyright © 2011 American Association for the Study of Liver Diseases [42].
