The proportion of ALT ( t = 49.710, P < 0.001), AST (t = 39.770, P < 0.001), TB (t = 10.370, P < 0.001), GGT (t = 25.100, P < 0.001), and LDH (t = 26.860, P < 0.001) levels greater than 2ULN in the prototype patients was significantly higher than in the Omicron BA.5.2 patients. Here, GPT is linked to tuberculosis.
