| GPT (U/L) | 0–40 | 33.87±5.22 | 119.86±19.83 | 52.78 | <0.001 |
| GOT (U/L) | 8–40 | 28.69±2.48 | 151.07±18.81 | 81.50 | <0.001 |

Data are reported as mean±SD. BMI: body mass index; GPT: glutamic pyruvic transaminase; GOT: glutamic oxaloacetic transaminase; TB: total bilirubin; LA: lactic acid. The chi-square test or the t-test was used for statistical analysis.
