This is an FDA Premarket Notification (510(k)) letter for the ARCHITECT STAT Troponin-I Immunoassay and ARCHITECT STAT Myoglobin Immunoassay. It confirms that the devices are substantially equivalent to legally marketed predicate devices.

However, the provided document does not contain any information about acceptance criteria, device performance studies, sample sizes, expert ground truth establishment, adjudication methods, or MRMC studies.

This type of FDA letter is an approval document, not a study report. To find the information you're looking for, you would typically need to consult:

• The original 510(k) submission document itself (which includes the detailed performance data).
• The device's Instructions for Use (IFU) or package insert, which often summarizes performance characteristics.
• Clinical studies or validation reports associated with the device, usually referenced or summarized in the 510(k) submission.

Since the provided text does not contain the requested information, I cannot complete the table or answer the specific questions about the study design, sample sizes, or ground truth.
