Logistic regression analysis revealed that MMP-2-735CC (OR = 5.39; 95% CI = 0.62–47.17; p = 0.238504) and -735CT genotype (OR = 7.22; 95% CI = 0.78–67.14; p = 0.072836), as well as MMP-9-1562CC (OR = 1.45; 95% CI = 0.31–6.70; p = 0.757914) and -1562CT genotype (OR = 1.60; 95% CI = 0.33–7.83; p = 0.548801) were associated with a higher risk of lung cancer. The gene discussed is MMP2; the disease is lung carcinoma.
