Summary

Summary

A network meta-analysis evaluating glucosamine and chondroitin (alone and combined) for pain and function in knee and hip osteoarthritis. Including the GAIT trial (n=1583) across 10 RCTs, no statistically significant difference from placebo was found overall. However, a subgroup with severe OA showed significant pain reduction with combination therapy. Separate studies suggest possible long-term cartilage protection. Safety profile is favorable.
