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. TMC checkmd: PREECHA TIEWTRANON, M.D. — สาขา ศัลยศาสตร์ตกแต่ง ( Plastic Surgery ); licensed since 1966, status current. [tmc] |
OFF | 26 | 2026-08-29 | |
| M2 | Identifiability of the responsible physician Physician(s) named with role and tied to this address. Named as founder with role, address and phone tied to the Sukhumvit 55 clinic. [site] |
SEC | 16 | 2026-08-29 | |
| 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 TMC checkmd; no licence number published by the clinic. [tmc] |
OFF | 8 | 2026-08-29 | |
| M4 | Facility registration Found with a spelling discrepancy; or the location is registered under the name of the host facility at the same address (a practice inside a hospital or a centre); or the value comes from a mirror or from a directory that shows no status — the profile names the record holder verbatim. MOPH Department of Health Service Support private-facility register, queried by name on 2026-09-20: ชื่อสถานพยาบาล คลินิกเฉพาะทางด้านเวชกรรมศัลยกรรมตกแต่งและผิวหนังเลเซอร์ พีเอไอ — สถานที่ตั้ง เลขที่ 898/3 ซอยสุขุมวิท 55 (ทองหล่อ) ถนนสุขุมวิท ตำบลคลองตันเหนือ อำเภอวัฒนา จังหวัดกรุงเทพมหานคร — เลขที่ใบอนุญาตประกอบกิจการ 10102000563 — ใช้ได้ถึงวันที่ 31 ธันวาคม 2572. Licensed name matches the trading name (PAI); the register records the house number as 898/3 while the clinic publishes 898/1 on the same soi, so the record is scored as found with an address discrepancy. [hss] |
OFF | 10 | 2026-09-20 | |
| M5 | Legal-entity traceability Only a brand, without a legal form and without a responsible person. Whatever we find ourselves is shown on the profile as a fact and does not raise this cell. Brand name only; no juristic-person name or registration number published. [site] |
SEC | 8 | 2026-08-29 | |
| M6 | Self-disclosure of identifiers Logos without numbers. Named professional-society roles (Chairman, ThPRS; Chulalongkorn Hospital unit head) but no licence, facility or company numbers. [site] |
SEC | 10 | 2026-08-29 | |
| M7 | Advertising honesty Systematic superlatives; systematic safety promises without an absolute; absolutes about the past (success rates, “no infection since …”, satisfaction figures, “we guarantee your satisfaction”); comparisons with surgery. Systematic soft superlatives on the clinic's own pages ('world-renowned', 'exceptional results', 'highest standards', 'leading aesthetic plastic surgeries'); no guarantee, '100%', or bare 'No.1/best' claim found. [site] |
SEC | 12 | 2026-08-29 | |
| M8 | Cross-locale consistency All load-bearing fields agree. Mechanical comparison of 2 language fronts (home, zh) on 2026-09-17: every matched physician name, phone number and published number appears on every front. [fronts] |
SEC | 5 | 2026-09-17 | |
| M9 | Patient documents None. No informed-consent, risk/contraindication, aftercare, revision-policy or complaint-route page found on the surveyed pages. [site] |
SEC | 5 | 2026-08-29 |
