How strong is the evidence for Compression?

A 2017 meta-analysis and an independent 2016 systematic review with meta-analysis both find compression garments modestly reduce muscle soreness and improve perceived recovery after exercise-induced muscle damage, though effects on objective performance measures like strength are smaller and less consistent. That evidence is currently rated emerging (38/100), built on 4 published studies, including 4 meta-analyses -- still too little to draw firm conclusions from.
