TNFα increased the risk of endometrial cancer in the diabetic population (ORQ4 vs. Q1 = 4.176, 95% CI 0.990–17.609, p = 0.052), whereas this effect is not seen in the entire population (ORQ4 vs. Q1 = 0.625, 95% CI 0.412–0.949, p = 0.024; adjusted p = 0.096). The gene discussed is TNF; the disease is endometrial cancer.
