  1. Missing cases were found in three variables; diagnosis (n = 18) (0.9 %), age groups (n = 1) (0.05 %), pain intensity (n = 1) (0.05 %). Tests used: Chi-square
  2. a Independent samples t-test
  3. b Only persons answering the question regarding pain were able to answer the pain-related sleep disturbance question (n = 1080)
