How to read this table
In short: benefit is what was observed; evidence is how much you should trust the observation. A “Benefit seen” tag on a weak study counts for far less than the same tag on a meta-analysis.

| knee function (topical ginger vs standard treatment) | No significant difference in knee function with topical ginger vs standard treatment was found. (95% CI, -1.15 to 0.13 (P = 0.12))No clear benefit | -0.51 points | — | — | Meta-analysis · 2020 | PMID 32214292 |
