Power Wheelchair Model 2200

The provided document is a 510(k) clearance letter from the FDA for a power wheelchair, Model PSB-2200 (also referred to as Model 2200). It focuses on the substantial equivalence of the device to a predicate device and its indications for use. The document does not contain any information regarding acceptance criteria, device performance metrics (such as sensitivity, specificity, accuracy), sample sizes for testing or training, ground truth establishment, or details of specific studies proving the device meets acceptance criteria.

Therefore, I cannot answer the questions directly from the provided text. The output of the desired information would be:

1. A table of acceptance criteria and the reported device performance: Not provided in the document.
2. Sample sized used for the test set and the data provenance: Not provided in the document.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable/provided as there's no mention of a ground truth for a test set.
4. Adjudication method for the test set: Not provided in the document.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable, as this is a physical medical device (power wheelchair), not an AI/imaging diagnostic device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable, as this is a physical medical device, not an algorithm.
7. The type of ground truth used: Not applicable/provided.
8. The sample size for the training set: Not provided in the document.
9. How the ground truth for the training set was established: Not applicable/provided.

The document is a regulatory clearance letter, not a clinical study report or technical specification detailing performance metrics.
