Spearman’s rho correlation analysis disclosed the significantly positive correlations of blood leukocyte RTL with AST (r = 0.51, P < 0.001), ALT (r = 0.51, P < 0.001), TB (r = 0.44, P = 0.020), and DB (r = 0.46, P = 0.011) in both tuberculosis patients with and without ATDILI. This evidence concerns the gene GPT and tuberculosis.
