And we found that the difference of age, TB, AST, ALT, HGB, WBC, PLT and ALB were not significant after PSM, just only the spleen volume (414.41 ± 210.77 vs 324.82 ± 206.34, p = 0.023) and the SNLR (0.38 ± 0.22 VS 0.30 ± 0.18, p = 0.029) were significant, indicating that the PSM results were credible. Here, CYGB is linked to tuberculosis.
