The x-axis is time from initiation of yoga classes. The y-axis is the modified 23-point Roland Disability Scale mean score. Higher scores reflect worse back pain–related function. The yoga group received hatha yoga classes weekly for the first 12 weeks of the study. Both groups received an educational book on self-care management of low back pain and continued their usual medical care. P values for any difference in mean Roland Disability scores between groups (calculated by comparing mean Roland change scores from baseline using the Wilcoxon rank sum test) are .29 and .28 at 6 and 12 weeks, respectively.
