  3. bincludes one borderline underweight participant
  4. cAverage weekday work hours were calculated from baseline work diaries
  5. dThe 36-item version of the Nordic Musculoskeletal Questionnaire [39], modified to measure problems in the last month. Issues identified as causing trouble were collapsed into categories of upper body problems (e.g., neck, shoulders, elbows, and wrists/hands), back problems (e.g., upper back, lower back, and hips/thighs/buttocks) or lower extremity problems (e.g., knees, and ankles/feet)
  6. e1 to 10 scale, higher numbers indicate more favourable workplace scores, or greater stress levels
  7. f1 to 100 scale, higher numbers indicate better quality of life
