GPT and hepatitis A virus infection: Similarly, median ALT levels at baseline were significantly higher in patients experiencing high grade hepatitis compared to lower grades (median (range) 88 IU/L (13 IU/–147 IU/L) vs. 37 IU/L (11 IU/L–146 IU/L), respectively; p = 0.037) and were not significantly associated with different HCC etiologies (infectious vs. non-infectious).
