Age- and sex- adjusted odds ratio on stroke risk by HO-1 genotypes by HDL-C level. Low HDL-C status is HDL-C level less than 40 mg/dL in men or 50 mg/dL in women. P-values in parenthesis were obtained for each subgroup comparing with the reference group (low risk and genotype S), and those p values of ≧0.05 were not showed. Bold p value near curved arrow was obtained for comparing risk of genotype L with S in the high risk factor profile group. NS: p ≧0.05. *: p < 0.05. **: p < 0.01. ***: p < 0.001
