The provided text is a 510(k) summary for a medical device (Modified Sterile Plate & Screw Kit Configurations for use with the Bioplate® Titanium Fixation System) and primarily focuses on establishing substantial equivalence to predicate devices, rather than presenting a performance study with specific acceptance criteria as would typically be seen for a new or novel device.

Therefore, the document does not contain the information requested regarding:

1. A table of acceptance criteria and reported device performance.
2. Sample size used for the test set and data provenance.
3. Number and qualifications of experts for ground truth establishment.
4. Adjudication method for the test set.
5. Multi-reader multi-case (MRMC) comparative effectiveness study or effect size.
6. Standalone (algorithm-only) performance.
7. Type of ground truth used (e.g., pathology, outcomes).
8. Sample size for the training set.
9. How ground truth for the training set was established.

Instead, the document states:

• Comparison of the device's technological characteristics with those of the predicate devices: "All the technical characteristics of the sterile plate and screw kit configurations for use Bioplate® Titanium Fixation System are substantially equivalent to the corresponding characteristics of the predicate devices, and any minor differences raise no new issues of safety and efficacy."
• The materials used have been implanted safely for many years.
• Sterilization validation and packaging validation studies were successfully completed, providing a high level of assurance of sterility.

The "acceptance criteria" in this context are effectively demonstrating that the device is substantially equivalent to legally marketed predicate devices, meaning it has the same intended use, similar technological characteristics, and raises no new questions of safety or effectiveness. The study proving this involves comparing the new device's specifications (materials, sterilization method, intended use) against those of established predicate devices.
