MMP7 and tuberculosis: As shown in Fig. 2, serum MMP-7 was positively correlated with DB (r = 0.634, p < 0.001), TB (r = 0.602, p < 0.001), GGT (r = 0.571, p < 0.001), TBA (r = 0.322, p < 0.001), AST (r = 0.266, p < 0.001), ALP (r = 0.230, p < 0.001), and ALT (r = 0.201, p < 0.01), and negatively correlated with AMY (r = -0.406, p < 0.001).
