Table 1. The breakdown of NASH and non-NASH patients according to serum AST level below and above the upper limit of normal, and serum AST level below and above two times the upper limit of normal, in a cohort of biopsy-proven NAFLD patients.

AST level (IU/L)	Non-NASH	NASH	Total
The upper limit of normal
AST <37	6	35	41
AST ≥37	4	48	52
Total	10	83	93
Two times the upper limit of normal
AST <74	10	67	77
AST ≥74	0	16	16
Total	10	83	93

Note: (I) a complete description of the study population is published elsewhere (9); (II) the diagnosis of NASH was based on pathologist global assessment; (III) the upper limit of normal of serum AST level at the author’s institution is 37 IU/L. AST, aspartate aminotransferase; NAFLD, non-alcoholic fatty liver disease; NASH, non-alcoholic steatohepatitis.
