Table 3 Registrations for people with intellectual disability stratified by type of living

	n (%)	Median (5-95 %)
Inpatient
None/some special housing	332 (10.2)	2 (1-14)
Special housing whole study	240 (5.1)	1 (1-8)
None/some vs special housing^a	OR = 0.48 (0.41–0.57)	p = 0.002
- Adjusted for age at study start	OR = 0.50 (0.42–0.60)
Outpatient
None/some special housing	656 (20.1)	4 (1-20)
Special housing whole study	784 (16.8)	3 (1-15)
None/some vs special housing^a	OR = 0.81 (0.72–0.90)	p = 0.001
-Adjusted for age at study start	OR = 0.84 (0.75–0.95)
Total
None/some special housing	714 (21.8)	4 (1-27)
Special housing whole study	842 (18.1)	3 (1-18)
None/some vs special housing^a	OR = 0.79 (0.71–0.88)	p < 0.001
-Adjusted for age at study start	OR = 0.82 (0.74–0.92)

Percentages based on number of people in each group, i.e. 3269 in none/some special housing and 4661 in special housing during the whole study period
Number of people with at least one registration during 2002–2012, and number of registrations per person with at least one, among people with intellectual disability
^aComparisons between number of people with at least one registration are made using odds ratios (ORs) with 95 % confidence intervals, whereas comparisons between number of registrations per person are compared using Mann-Whitney U-test
