Research findings
Filter-difference study
Against the 21-record Surgical Robot Endoscopy Instruments Keyword Candidate Study, this 19-record cohort shares 19 records. Only 0 occur here and 2 only in the reference; the union contains 21. These are filter-membership differences, not company entries or exits.
| Company cohort | Directly linked pages | Share of public archive | Archive date |
|---|---|---|---|
| 19 | 19 | 0.1% | 2026-10-16 |
Deduplicated company IDs.
Filter differences and comparison link
The largest recorded sub-industry participation gap is for Surgical instruments and robots: 12/19 here versus 12/21 in the reference, an absolute difference of 6.0 percentage points. The cohorts have overlapping company IDs and are not independent samples.
| sub-industry | Focal count/base | Reference count/base | Participation gap (pp) |
|---|---|---|---|
| Surgical instruments and robots | 12/19 | 12/21 | +6.0 |
| Orthopaedic and dental implants | 0/19 | 1/21 | -4.8 |
| Medical imaging equipment | 3/19 | 4/21 | -3.3 |
| Medical-equipment core components | 1/19 | 1/21 | +0.5 |
| Industrial borescopes and oil-condition monitoring | 1/19 | 1/21 | +0.5 |
Zero means no recorded label, not no business; multi-label cells overlap.
