  1. aAfter the ramping phase week 8, bAfter the maintenance phase week 19, cAt two months follow-up
  2. dEach scale score indicates the percentage of time in the previous two weeks when the respondent was limited in performing a specific dimension of job tasks (from low to high rate of difficulty in performing job demands). The minimum score is 0 (limited none of the time) to 100 (limited all of the time)
  3. eFive items addressing difficulty in scheduling demands
  4. fSix items covering difficulty in performing cognitive tasks involving the processing of sensory information and a person’s problems interacting with people on-the-job.
  5. gFive items addressing decrements in the ability to meet demands for quantity, quality and timeless of completed work
  6. hA percentage estimate of work loss based on the weighted sum of the scores from the Work Limitations Questionnaire WLQ scales
  7. iWarwick-Edinburgh Mental Well-being Scale WEMWBS: Scores range 14 to 70. Higher scores indicate better positive mental well-being
