The provided 510(k) summary (K120920) describes the acceptance criteria and the study that proves the device meets them.

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample Size Used for the Test Set and Data Provenance

The document does not specify a distinct "test set" in the context of clinical data. The performance evaluation was conducted according to technical standards (ISO 17510-2). The document indicates "No clinical test was performed for this device." Therefore, there is no sample size for a clinical test set, nor data provenance (country of origin, retrospective/prospective).

3. Number of Experts Used to Establish Ground Truth and Qualifications

Not applicable as no clinical study or ground truth established by experts was performed for the performance evaluation. The evaluation was based on engineering measurements against a technical standard.

4. Adjudication Method for the Test Set

Not applicable as no clinical study or expert adjudication was performed.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No MRMC comparative effectiveness study was done. The device is a physical medical device (CPAP masks), not an AI-assisted diagnostic or imaging device, so this type of study is not relevant.

6. Standalone (Algorithm Only) Performance

Not applicable. The device is a physical medical device, not an algorithm. The performance evaluation was conducted on the physical properties of the masks.

7. Type of Ground Truth Used

The "ground truth" for the performance evaluation was established by the technical requirements and thresholds defined in ISO 17510-2: "Sleep apnea breathing therapy-Part 2: Masks and application accessories." This is a set of engineering standards, not expert consensus, pathology, or outcomes data in the traditional sense of a clinical study.

8. Sample Size for the Training Set

Not applicable. The device is a physical medical device; there is no "training set" like there would be for a machine learning algorithm.

9. How the Ground Truth for the Training Set Was Established

Not applicable for the same reasons as point 8.
