Table Key:
- Pain intensity was from 0–10 numeric rating scale; region specific disability was from z-scores derived from validated questionnaires for neck, shoulder, back, and knee disability; Physical and mental component summary was from Medical Outcomes Survey-Short Form; Comorbidity was from the Charlson and Functional Comorbidity Indices
- OSPRO-YF = Optimal Screening for Prediction of Referral and Outcome Yellow Flag Tool; OSPRO-ROS = Optimal Screening for Prediction of Referral and Outcome Review of Systems Tool; YF-10 or ROS-10 = 10 item version of the tool; ROS+ = additional 13 items of the OSPRO-ROS.
