Summary

This study looked at whether adding vitamin D supplements to physical therapy helps people with long-term low back pain. 200 adults from Saudi Arabia took part, with some getting physical therapy alone and others getting physical therapy plus vitamin D for six weeks. Researchers measured pain, disability, and blood markers to see if the combination worked better.
