Question: Does patient Priority Weighting of the Roland Morris Disability Questionnaire Change Results of the Lumbar Epidural Steroid Injections for Spinal Stenosis Trial?
Answer: Results of the LESS trial did not substantively differ based on re-analysis of data using RDQ with SIP weights or patient-prioritized RDQ outcomes. This provides additional evidence that epidural injection of corticosteroid+lidocaine offered minimal or no short-term benefit as compared with epidural injection of lidocaine-alone for older adults with lumbar spinal stenosis.
