The associations between the MUC2 expression level in CRC tissues and other clinicopathological characteristics were investigated The meta-analysis demonstrated that a low level of MUC2 expression did not show an association with gender (female versus male: RR, 0.92; 95% CI, 0.82–1.04; P = 0.20; Figure 3(f)), histological grade (RR 1.19; 95% CI, 0.95–1.50; P = 0.13; Figure 3(g)), depth of invasion (T3, T4 versus T1, T2: RR, 1.03; 95% CI, 0.66–1.62; P = 0.89; Figure 3(h)), and distant metastasis (positive versus negative: RR, 1.13;95% CI, 0.92–1.38; P = 0.24; Figure 3(i)). Here, MUC2 is linked to colorectal carcinoma.
