Google Maps listing (reference, not scored)
What the clinic's public Google Maps listing showed when we read it: the rating other people gave, the number of their reviews and the hours the clinic itself publishes there. This block is a reference only — it does not enter the score, the rank, the ceilings or the holds, and we have not checked it beyond matching the listing to this record.

Axis by axis
rubric value 1–5 · ? could not verify (no points, not a negative finding) · — not applicable: this country has no register of that class · OFF official register · SEC secondary source
| Axis | Finding (rubric anchor) | Value | Source class | Weight | Checked |
|---|---|---|---|---|---|
| M1 | Specialist certification of the responsible physician Found, status current; the registered specialty matches what this physician advertises. HealthPro (FPS Public Health): Mertens Marianne, specialities MBS45 (plastic, reconstructive and aesthetic surgery), qualification code 210, status active, practice address matches ("Dr. Marianne Mertens BVBA", Sint Michielskaai 8, 2000 Antwerpen).

| M2 | Identifiability of the responsible physician Physician(s) named with role and tied to this address. |
SEC | 16 | 2026-08-31 | |
| M3 | Basic medical licence Matched by name (surname stem and given name or initial; a second identifier where the name is ambiguous). Matched by name in HealthPro (nihdi 11611195). [healthpro] |
OFF | 8 | 2026-08-31 | |
| M4 | Facility registration Could not verify — no points, counts against coverage, not a negative finding. Reason: Queried, no match. Last attempt: facility_registry, 20 September 2026 — recordsTotal 0 on every leg. The register covers the whole of Flanders, where this treatment address lies, and the positive control Name=Universitair Ziekenhuis Gent returned recordsTotal 2 in the same session. Belgian law recognises hospitals, not private clinics, so the absence of a row is the expected state and is not a finding about this clinic. Queried in the Flemish care-facility register (CoBRHA Viewer) by enterprise number and by name; no row returned. Belgian law recognises hospitals, not private clinics, so this axis carries no value for a private practice. |

| M5 | Legal-entity traceability The clinic names the legal entity or the responsible person in its legal notice and the record is found by name; or the number the clinic publishes leads to an entity with a different name that is tied to this location by the same address or the same responsible person. Matched by name and address in KBO/BCE ("Dr. Marianne Mertens, plastische, reconstructieve en esthetische heelkunde", enterprise 0697.931.628, Sint-Michielskaai 8, 2000 Antwerpen); the registration number itself is not published on the clinic's own site.

OFF | 8 | 2026-08-31 | |
| M6 | Self-disclosure of identifiers Logos without numbers. Professional affiliations (EBOPRAS examiner, UEMS, VBS/GBS board) named without membership or licence numbers. [site] |
SEC | 10 | 2026-08-31 | |
| M7 | Advertising honesty One or two soft superlatives or non-absolute safety promises. One soft superlative on the clinic's own Dutch page ("gerenommeerd" / renowned). [site] |
SEC | 12 | 2026-08-31 | |
| M8 | Cross-locale consistency Could not verify — no points, counts against coverage, not a negative finding. Reason: Single language front. Last attempt: clinic_site, 17 September 2026 — one language front; no hreflang alternates or language links The clinic site publishes one language front; nothing to compare. |
? | ? | 5 | 2026-09-20 |

These cells score nothing and are not negative findings. A cell on a register that is closed to machine queries is left out of the coverage calculation; the others count against it. Each one names why it is empty; an attempt that did not complete is re-run in the next collection pass. If you can point to a public source, send it.
