For the IL1B polymorphism, the association under codominant and recessive models was insignificant after adjustment for covariates (age, diabetes mellitus, dyslipidemia), however with the dominant model, the risk of stroke with CT-CC was 2.3 higher than for TT homozygotes (2.30 (1.36–3.87); p = 0.020) (Table 3). The gene discussed is IL1B; the disease is diabetes mellitus.
