1Derived from analysis of covariance that evaluated the associations between major cardiovascular risk factors (dependent factor) and blood group (independent factor), after adjustment for age (in years) and sex.
2Mean (SD) (all such values).
3Number (percentage in individual group) (all such values).
4,5Significantly different from AB blood group (ANOVA with Bonferroni's correction): 4 P < 0.05, 5 P < 0.01.
A indicates A blood group; B indicates B blood group; O indicates O blood group; AB indicates AB blood group; TC: total cholesterol; TG: triglycerides; HDL-c: high density lipoprotein cholesterol; LDL-c: low density lipoprotein cholesterol; WC: waist circumference.
