2. Sample Size Used for the Test Set and the Data Provenance

The document states that "Representative samples for the device underwent load and repeatability testing to verify functional and performance characteristics." It does not specify the exact sample size for these tests. There is no information provided regarding data provenance (e.g., country of origin of the data, retrospective or prospective) for any of the testing mentioned.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts

Not applicable. This device is a medical treatment chair, and its performance is evaluated against engineering standards and functional requirements, not against ground truth established by experts in a diagnostic context.

4. Adjudication Method for the Test Set

Not applicable, as the testing involves engineering and performance standards rather than subjective assessments requiring adjudication.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was Done

No, a Multi Reader Multi Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for diagnostic devices that involve human interpretation of images or data, which is not the case for a medical treatment chair.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done

Not applicable. The device is a physical medical chair and does not involve an algorithm for standalone performance. Its performance is assessed through physical and electrical testing against established standards.

7. The Type of Ground Truth Used

The ground truth for this device is based on engineering standards, functional specifications, and safety requirements. This includes:

Specified weight capacity (200 kg).
Compliance with various ISO, IEC, AS/NZS, BS EN standards for biocompatibility, electrical safety, EMC, flame retardancy, quality management, risk analysis, and component specifications (e.g., castors).
Internal "self-imposed load and repeatability test requirements" to verify functional and performance characteristics.

8. The Sample Size for the Training Set

Not applicable. As a physical medical device, there is no "training set" in the context of machine learning or AI.

9. How the Ground Truth for the Training Set was Established

Not applicable, as there is no training set for this device.
