GREECS, Greek acute coronary syndrome; CVD, cardiovascular disease.
Low education was defined as<9 years of school, intermediate education as 9-14 years of school, and high education as>14 years of school.
Chi-square test was used to compare baseline factors between groups.
Analysis of variance was used to compare baseline factors between groups.
p<0.01 for comparisons between the high- and intermediate-education group versus the low-education group, after using the Bonferroni rule to correcting for the probability of the inflation of type I errors due to multiple comparisons.
