The provided text is a 510(k) summary for the Cynosure PhotoSilk Plus Pulsed Light System and Laser Attachment. It explicitly states "Nonclinical Performance Data: none" and "Clinical Performance Data: none".

Therefore, based on the provided document:

1. A table of acceptance criteria and the reported device performance: Not applicable. No performance data or acceptance criteria are provided.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): Not applicable. No test set data is provided.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience): Not applicable. No ground truth establishment for a test set is mentioned.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. No test set or adjudication method is mentioned.
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. No MRMC study or AI assistance is mentioned as this device is a medical laser system, not an AI diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This device is a laser system and does not involve algorithms or standalone performance testing in this context.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable. No ground truth is mentioned.
8. The sample size for the training set: Not applicable. No training set is mentioned.
9. How the ground truth for the training set was established: Not applicable. No training set or ground truth for it is mentioned.

Conclusion: The 510(k) submission for the Cynosure PhotoSilk Plus Pulsed Light System and Laser Attachment did not include any nonclinical or clinical performance data. The device's substantial equivalence was based on its similarity to predicate devices in terms of indications for use, principle of operation, and similar performance specifications, rather than new performance data with acceptance criteria.
