  2. SSLU-Small Segregated Living Unit; LILU-Large Integrated Living Unit; SILU-Small Integrated Living Unit.
  3. 1The total n for this item is 47 because of one missing answer.
  4. 2Results of the χ2 test may be invalid because the frequency is zero in several cells.
  5. 3Reffering group are the LU where meals are prepared.
