Variable	Negative breath test (n = 32)	Positive breath test (n = 24)	p
ALT surgery	0.592 ± 0.41	0.545 ± 0.23	0.802
ALT BT	0.522 ± 0.21	0.514 ± 0.33	0.266
AST surgery	0.516 ± 0.65	0.442 ± 0.16	0.352
AST BT	0.462 ± 0.15	0.428 ± 0.18	0.259

The variables are expressed as mean ± SD (standard deviation). Statistical analysis was done using Student’s t test

ALT, alanine aminotransferase; AST, aspartate aminotransferase; BT, breathing test
