Partial correlation analysis showed that serum GP73 was positively correlated with TB (r = 0.455, P < 0.001), ALT (r = 0.206, P < 0.007), AST (r = 0.354, P < 0.001), and TBA (r = 0.413, P < 0.001), while negatively correlated with ALB (r = −0.465, P < 0.001) (Table 2). This evidence concerns the gene GPT and tuberculosis.
