Odds ratios (intellectual disability group vs. control group) for those with ≥1 registration/visit for 2002–2012. Comparisons are made independently (2002–2012) for each year, for the intellectual disability group in relation to the control group, and for planned inpatient registrations (a), unplanned inpatient registrations (b), planned outpatient visits (c), and unplanned outpatient visits (d) respectively. Each circle represents one 5-year age group. Age groups are presented in order with the youngest age group to the left and the oldest to the right for each year. Only age groups with more than 100 individuals are presented here. All data are presented in the Additional file 1
