Pilot clinics are selected against explicit criteria. Baseline and follow-up indicators use the same definitions. The next cohort receives a version of the model that reflects both the original design and what the field has learned.
Local language, compliance requirements, clinic economics and team capability are treated as design constraints. A result in one clinic is not presented as proof that every market will respond identically.
Commercial performance is separated from clinical efficacy. The programme supports patient understanding and adoption; it does not replace the surgeon's clinical recommendation or promise a patient outcome.
