How reliable is the 91.6% knee pain improvement claim, and what kind of studies is it based on?

Based on small non controlled studies

Not from large randomized clinical trials

Evidence exists but strength is weak

Based mainly on preliminary clinical research

Looks promising but research is limited

Based on early research not definitive

Good results so far still early

Real studies just not huge ones

Seems helpful but science still catching up

Encouraging numbers needs more testing

Small studies but results look positive

Comes from early research not hype
