BDI = Beck Depression Inventory; BMI = body mass index; CI = confidence interval; MCS = Mental Component Summary; NDI = Neck Disability Index; NHP = Nottingham Health Profile; NR = not reported; NSAID = nonsteroidal anti-inflammatory drug; PCS = Physical Component Summary; PSFS = Patient Specific Functional Scale; SF-36 = Short-Form 36 questionnaire; VAS = visual analog scale
Unless otherwise noted, followup time is calculated from the end of the treatment period
Cluster RCT where clusters were formed from participants working on the same floor
Intervention lasted 12 months and followup is at the end of the intervention
Cluster RCT where clusters were formed from participants selecting a time that best fit their schedule
Neck disability scale was created by investigators from responses to eight questions related to functional limitations due to pain; this scale is not the same as the more common NDI
