Table 3 Multivariate regression model of cost drivers

From: Cost of diagnosing dementia in a German memory clinic

  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
Final diagnosis (reference: dementiab) 356.3 (88.1)** 181.8 530.8
Number of existing illnesses and previous surgeries – 4.8 (15.3) – 35.1 25.5
Number of drugs regularly taken – 4.1 (12.5) – 28.8 20.6
Intercept 133.3 (392.8)* – 645.1 911.8
  1. Linear mixed model: 120 observations, p = 0.003
  2. *p < 0.01, **p < 0.001 (statistically significant)
  3. aAccording to Mini-Mental State Examination (MMSE): values reverse coded, range 0–30, higher scores indicate better cognitive function
  4. bReferring to the following ICD-10 diagnoses: F00.0, F00.1, F01.1, F00.2, F02.0, and F03
  5. b observed coefficient, SE standard error, CI confidence interval, ICD International Statistical Classification of Diseases and Related Health Problems
