MSK = musculoskeletal; QST = quantitative sensory testing.
Completion rate for each task was calculated as the number of participants with effective QST data out of the number of participants who participated in that task.
Completion rate for all QST tasks was calculated as the number of participants with effective QST data for the pressure tasks (at the forearm and trapezius), heat task, cold pressor task, TSP task, and CPM task, out of the number of participants who attended laboratory visit for QST assessment.
