Table 3 Multivariate regression model of cost drivers

	Total cost of diagnostic procedure
	b (SE)	95% CI
Age	0.1 (4.2)	– 8.2	8.4
Sex (reference: female)	– 71.3 (70.8)	– 211.5	69.0
Severity of dementia (MMSE)^a	11.3 (7.9)	– 4.3	27.0

Number of drugs regularly taken	– 4.1 (12.5)	– 28.8	20.6
Intercept	133.3 (392.8)*	– 645.1	911.8

Linear mixed model: 120 observations, p = 0.003
*p < 0.01, **p < 0.001 (statistically significant)
^aAccording to Mini-Mental State Examination (MMSE): values reverse coded, range 0–30, higher scores indicate better cognitive function
^bReferring to the following ICD-10 diagnoses: F00.0, F00.1, F01.1, F00.2, F02.0, and F03
b observed coefficient, SE standard error, CI confidence interval, ICD International Statistical Classification of Diseases and Related Health Problems
