The provided text is a 510(k) premarket notification approval letter for the Visualine® II (SunLine®) Barbiturates Test. It confirms that the device is substantially equivalent to legally marketed predicate devices. However, this document does not contain the detailed study information required to answer your specific questions about acceptance criteria and device performance studies.

The letter indicates the device's intended use: "qualitative testing for the presence of Secobarbital in urine samples at or above 300 ng/ml." It also states that the test provides a preliminary screening result and recommends a more specific alternative method for confirmation.

To address your questions directly, information regarding acceptance criteria, study design, sample sizes, ground truth establishment, expert qualifications, adjudication methods, and comparative effectiveness studies would typically be found in the 510(k) submission document itself or associated clinical study reports, which are not part of this approval letter.

Therefore, I cannot provide the requested table and study details based solely on the provided text. The document is an FDA approval letter, not the technical study data.
