Systematic review and network meta-analysis on the efficacy and safety of parmacotherapy for hand osteoarthritis
PloS one (2024) · Meta analysis · n=3965
GCSB-5, a specific herbal complex that mainly regulate pain in hand osteoarthritis, showed the greatest reduction in pain [WMD = -13.00, 95% CI (-26.69, 0.69)].
Large meta-analyses show minimal to nonexistent benefits. Effects appear modest at best, with significant study heterogeneity. Combination with glucosamine may be more effective than chondroitin alone.
