GPT and fatty liver disease: After excluding the HCV genotype (P = .810), serum creatinine (Cr) (P = .997), and sodium (Na) (P = .388), univariate linear regression modelling selected BMI, HCV RNA, METAVIR F stages, ALT/ULN (40 IU/L) categories (model 1), ActiTest A scores (model 2) and METAVIR A grades (model 3), hepatic steatosis categories, bilirubin, INR, and platelet count (all P < .25), in addition to age (P = .001) and sex (P = .425), for the subsequent stepwise multiple linear regressions.
