The descriptive

clinical data were initially examined with respect to five racial and ethnic categories (e.g., non-Latino white, non-Latino black, Latino, Asian, and “other”), and these data are primarily displayed in Tables 1-3. Smaller sample sizes in the non-Latino black, Asian, and “other” racial and ethnic categories precluded more detailed analyses. Detailed analyses and statistical assessments of risk factors associated with NASH histology and advanced fibrosis were conducted in participants who self-identified as either non-Latino Y-27632 solubility dmso white or Latino. Because there was only 1 individual who self-identified as Latino black, this person was omitted from the analyses due to the likelihood that Latino black individuals may be culturally and genetically different from the other Latino individuals included in the NASH CRN studies. Associations between clinical characteristics and NAFLD histology (i.e., NASH versus non-NASH histology and mild versus advanced fibrosis) among non-Latino whites and Latino individuals were investigated using univariate

and multivariate logistic regression models. Stepwise logistic regression analysis RGFP966 cost was used to identify significant predictors from among the following candidate predictors at enrollment: AST, ALT, total bilirubin, platelet count, triglycerides, total cholesterol, HDL cholesterol, LDL cholesterol, GGT, albumin, alkaline phosphatase, hyperlipidemia, metabolic syndrome, family history of NAFLD, acanthosis nigricans, palmar erythema, education level, income, total caloric intake, percent of calories from fat, percent of calories from carbohydrate, and physical activity. The P value for addition or elimination from the models was P < 0.05, and the models were forced to include terms for age, gender, and ethnicity. We also explored potential effect modification between ethnicity (i.e., Latino versus non-Latino white) and other covariates on the risk of NASH and advanced fibrosis. For all analyses, SAS 9.1 (SAS Institute, Inc., Cary,

NC) was for utilized. We considered differences statistically significant when P values were <0.05. Statistical interactions were considered statistically significant when P values were <0.001. Nominal two-sided P values were used. There were 1,026 adults with liver biopsy histology obtained within 6 months of enrollment, including 77 individuals with NASH-induced cirrhosis. Of the 1,026 adults included in this study, 37% (N = 377) were men, mean (95% CI) age was 48.8 (48.1-49.6) years, mean BMI was 34.2 (33.8-34.6) kg/m2, and mean WC was 108 (107-109) cm. Median (95% CI) AST was 43 (41-44) and ALT 58 (57-61) IU/L. Among the participants, 77% (N = 785) were non-Latino white, 12% (N = 118) were Latino, 3% (N = 27) were non-Latino black, 5% (N = 54) were Asian, and 4% (N = 42) were other race/ethnicity.
