Results revealed that FoxM1 expression was not associated with the gender (OR = 1.07, 95%CI = 0.82–1.39, P = .61, fixed effect), age (OR = 1.11, 95%CI = 0.84–1.45, P = .46, fixed effect) and differentiation (OR = 0.64, 95%CI = 0.37–1.10, P = .11, random effect) in CRC patients (Fig. 3A–C, Table 2). The gene discussed is FOXM1; the disease is colorectal carcinoma.
