^aAfter the ramping phase week 8, ^bAfter the maintenance phase week 19, ^cAt two months follow-up
^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)
^eFive items addressing difficulty in scheduling demands
^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.
^gFive items addressing decrements in the ability to meet demands for quantity, quality and timeless of completed work
^hA percentage estimate of work loss based on the weighted sum of the scores from the Work Limitations Questionnaire WLQ scales
ⁱWarwick-Edinburgh Mental Well-being Scale WEMWBS: Scores range 14 to 70. Higher scores indicate better positive mental well-being
