  "1. A table of acceptance criteria and the reported device performance": {
    "Acceptance Criteria": "Not explicitly stated in terms of specific performance metrics (e.g., hair reduction percentage, number of side effects). The submission focuses on substantial equivalence to the predicate device in terms of safety and effectiveness.",
    "Reported Device Performance": "The DeLight™ II HR System demonstrated safety and effectiveness in an IRB-approved human clinical trial. Clinical results and comparison to published data on the predicate device (EpiLight® Hair Removal System) showed substantial equivalence. Details on specific clearance rates or incidence of side effects are not provided in this summary."

  "2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)": {
    "Sample Size for Test Set": "Not specified in the provided text. The text only mentions 'various skin types and various hair colors were treated'.",
    "Data Provenance": "The clinical trial was an IRB-approved human clinical trial. The country of origin and whether it was retrospective or prospective is not explicitly stated, but clinical trials are typically prospective."

  "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. The device is a hair removal system, and the 'ground truth' would likely be objective measurements of hair reduction and observed side effects, which wouldn't require expert consensus in the same way an imaging diagnostic device would.",
  "4. Adjudication method (e.g. 2+1, 3+1, none) for the test set": "Not applicable. Adjudication methods are typically relevant for subjective assessments, which are not detailed for this device.",
  "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. This is a light-based hair removal device, not an AI-assisted diagnostic tool for human readers.",
  "6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done": "Not applicable. This is a physical medical device, not an algorithm, and it is used by healthcare professionals.",
  "7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)": "The clinical performance data was based on \"Clearance rates and occurrence of side effects were examined.\" This suggests a combination of objective measurements (clearance rates, likely percentage of hair reduction) and observed outcomes (side effects).",
  "8. The sample size for the training set": "Not applicable. This device is not an AI algorithm that undergoes a distinct 'training' phase in the conventional sense. Its development would involve engineering and clinical validation rather than machine learning training.",
  "9. How the ground truth for the training set was established": "Not applicable. See point 8."
