Table 3:

Regression models for the association between Sleep Problems and SCD in the two cohorts. Models adjusted for age, sex, education, comorbidities, sleep medication and medication affecting cognition. Further adjustment for general objective cognitive performance. SCD reference category=0. 1=1 complaint, 2=2 or more complaints.
