Association between education level and ideal cardiovascular health score stratified by income categories. Prevalences data are presented as percentages (95% CI) unless otherwise stated. Prevalences and their 95% CIs are calculated taking into account the complex survey design and using population-based weights. Standard errors are clustered at the primary sampling unit level. P values in A and B were calculated with “Primary education” as the reference group, whereas the P values in C were calculated with “No education” as the reference group
