Associations of MMP-7 rs11568818 (allelic model, I2 = 0.0%, p = 0.868; recessive model, I2 = 0.0%, p = 0.962) were found in all populations and (allelic model, I2 = 23.7%, p = 0.269; recessive model, I2 = 0.0%, p = 0.494) in Asians with bladder cancer risk, MMP-7 rs11568818 (allelic model, I2 = 0.0%, p = 0.583) in Asians with CC risk and (allelic model, I2 = 0.0%, p = 0.566; recessive model, I2 = 12.6%, p = 0.285) in Asians with CRC risk. Here, MMP7 is linked to urinary bladder carcinoma.
