Figure 2.

Performance of NAFL and NASH patients in d2 test. (A) Number of total responses (TR), (B) right answers (RA), and (C) total effectiveness (TOT), which was calculated by: TOT= TR − (O + C). (D) Concentration index (CON), which was calculated by: CON = RA − C. (E) Number of errors by Omission (O), Comission (C), and total errors (O + C). Results are the mean ± SEM. * p < 0.05; ** p < 0.01; *** p < 0.001; **** p < 0.0001 vs. control group (CNT). NAFL, NASH, patients with nonalcoholic fatty liver and nonalcoholic steatohepatitis, respectively.
