^aCI= Confidence interval selected because of data being stratified; ^b= 99% and 100 = 100% of people consumed from the cereal group [A]; [B] and [C]: different symbols indicate which mean DDS values (comparing the four geographical areas) are significantly different, Bonferroni multiple comparison test, p < 0.05. * Significant relationship between geographic group and whether or not subjects consume food from a specific group, Chi-square test, p < 0.05. Significant relationship between geographic group and whether or not subjects consume food from a specific group, Chi-square test, p < 0.01. *Significant relationship between geographic group and whether or not subjects consume food from a specific group, Chi-square test, p < 0.001.
