The review context is not an independent clinical trial; no difference does not certify equivalence. Parent 2975 and its s0/s1 claims share the original 2BFit citation/trial context and counterview mentions of the 2023 app, 2014 bracing and 2017 review. The same people, ankles, arms, events, times, citations, related sheets and review-included trials are not newly added as independent trials/participants.
