Low Back Pain Trajectories of U.S. Active-Duty Military Personnel Receiving Usual Medical Care Plus Chiropractic Care vs. Usual Medical Care Alone: Secondary Analysis of a Clinical Trial

This is a statistical analysis plan for a secondary analysis of data from a clinical trial. The project aims is to evaluate the effect of chiropractic care on low back pain trajectories. We will use weekly text message responses to describe and evaluate the 1-year pain trajectories of participants in a clinical trial comparing usual medical care plus chiropractic care to usual medical care alone for active-duty U.S. military members with low back pain.
