A4.13 Cohort sizes ranged from 55 to 1149 and the follow-up period ranged from two to six
years. Dietary assessment was by a simple questionnaire in two studies and by food
frequency questionnaire in the other (El Aidi et al., 2011). All studies investigated
consumption of acidic foods and drinks in relation to tooth wear. Multivariate
logistic regression analysis was used in all studies to explore associations. The
confounders considered by the studies investigating carbohydrate and dental
caries risk have been summarised in Table A4.2. Only one study reported its
funding sources which were mainly commercial (El Aidi et al., 2011); 67% of studies
did not report funding sources.
