Preparation variance keeps the evidence base uninterpretable
Platelet-rich plasma systems sold under the same general description produce preparations differing by up to eightfold in platelet concentration, with different leukocyte content and activation, which means published trials are studying materially different interventions under one name. Around 74% of studies use non-comparable protocols. Commercially this keeps payers from covering the category and confines roughly 31% of market value to direct patient payment, and it also means a manufacturer who standardises its own preparation and trials that specific product holds evidence nobody else can claim. That evidence would be uncontestable rather than merely favourable.
