Patients with a higher ratio of aspartate aminotransferase to alanine aminotransferase had a longer duration of parasite clearance (median duration: 8 days, 95% CI: 6–9 vs. 7 days, 95% CI: 5–8; p = 0.0050) than that of patients with imported malaria with a normal level of the ratio of aspartate aminotransferase to alanine aminotransferase. Here, GPT is linked to malaria.
