We also aimed to demonstrate whether there was any additional risk besides mortality associated with the presence of comorbidities; only the IL6 rs2069869 GG genotype was associated with mortality risk in patients with diabetes in the pA/H1N1 group (p = 0.011; OR = 40.8, 95% CI: 2.31–720.24). The gene discussed is IL6; the disease is diabetes mellitus.
