  1. CI, confidence interval; OR = odds ratio. 1 The numbers of subjects are not the same as in Table 4 because those with missing information relating to one or more of the socio-demographic covariates in the models (n = 187; 8% of the total) were excluded. 2 ORs from multivariate logistic regression models, adjusted for age, education, gender and religion of parent, and age and gender of the child. 3 The numbers do not add up to the total because of missing answers.
