Interest in cell treatment abroad: measure demand without inventing a trend
Search indices, enquiries and bookings are different measures. None proves that a treatment works, is authorised or is increasingly accepted by regulators.
Define the measure before describing a trend. A search index is relative to the selected query, place and period; it is not a patient count. Website traffic, enquiries, consultations, deposits, completed trips and treated patients are separate funnel stages. A multiplier claim is unusable without the exact source, extraction date, denominator and reproducible method.
Separate attention from clinical access. News coverage, advertising, social media, travel recovery and changes in terminology can move online interest without changing evidence or lawful availability. Visibility, followers, testimonials and media mentions are not outcome measures or regulator endorsements.
For a defensible demand study, pre-register queries, countries, dates and exclusions; preserve raw exports; report absolute counts where the source permits; and distinguish unique people from repeated events. Record platform and tracking changes. Do not attribute change to insurance, waiting times or regulation unless the design tests those explanations.
For a clinic cohort, report the full denominator from first eligible enquiry through assessment, consent, treatment and follow-up. State why people were excluded or withdrew and how many were lost to follow-up. Reporting outcomes only among people who travelled or replied after treatment creates selection bias and cannot establish effectiveness.
Use demand data for service planning, not medical persuasion. Verify any proposed ATMP through the EMA/HMA patient warning and seek independent clinical advice. Even a measurable rise in interest would not turn an unregulated or unsupported intervention into an authorised treatment.
