Therefore, the requested information regarding acceptance criteria and a study proving the device meets these criteria cannot be extracted from this document. The letter states that the device is "substantially equivalent" to legally marketed predicate devices, which is the basis for its clearance, not necessarily a demonstration of meeting specific performance criteria through a new study.
The document does not contain the following information:
- A table of acceptance criteria and reported device performance.
- Sample sizes used for the test set or data provenance.
- Number or qualifications of experts used to establish ground truth.
