  1. Frequent contacts are defined as 2 or more contacts to GPs on call in primary care sector and emergency room contacts during the last 3 months before child’s cancer diagnosis; OR Odds Ratio, CI confidence interval. For each socioeconomic variable, the models are adjusted for sex, diagnostic group (as an interaction term in the model, where we estimate the OR for each diagnostic group), diagnosis period and age at diagnosis (continuous), highest parental education in the household and household cohabitation status. a Due to few observations, logistic regression analysis did not reach convergence.
