For all lymphoma patients, the results of logistic regression analysis showed that patients with CA/CC genotype of IL6R rs2228145 had higher stage than patients with AA genotype under the dominant model (OR = 2.682, 95% CI = 1.084–7.033, p = 0.034), and patients with CA genotype had higher stage than patients with AA genotype under codominant model (OR = 2.741, 95% CI = 0.999–7.520, p = 0.048). The gene discussed is IL6R; the disease is lymphoma.
