  1. OR odds ratio; 95% CI 95% confidence interval
  2. CD group: older people who continued living in the community during the 5-year follow-up
  3. † The reported values of the intercept are odds with 95% confidence intervals
  4. ‡ The odds of antipsychotic prescriptions in the NH group in periods more than 3 months before institutionalisation were 2.58 times higher than the odds in the CD group
