  1. Total number of patients (n) per item in brackets
  2. *Prevalence difference in percent. It was calculated by subtracting the prevalence of "harm reduction-oriented" centres from the prevalence of the "rehabilitation-oriented" centres.
  3. **P-values estimated for prevalence difference
  4. † Prevalence difference ("rehabilitation-oriented" vs. "intermediate" centres) 5% (4%; 9%), p-value < 0.001)
  5. ††Not all items in each patient questionnaire were completed, thus the total number of respondents for each item varied from the total number of patients at each centre.
