This document does not describe a study involving AI/ML performance, human readers, or expert adjudication for image analysis. Instead, it focuses on the non-clinical performance testing of a new medical device connector (NRFit™) to demonstrate its substantial equivalence to a predicate device. The acceptance criteria and the "study" that proves the device meets them are based on these non-clinical, bench-top tests, primarily conforming to existing ISO standards.
Therefore, for aspects related to AI/ML, human readers, expert ground truth, and training data, the response will state that this information is not applicable to this type of device submission.
Here's the breakdown of the information requested:

2. Sample Size Used for the Test Set and the Data Provenance
This document does not specify a "test set" in the context of AI/ML or image data. The testing described is non-clinical (bench testing) for device components. The sample size for each specific non-clinical test (e.g., number of connectors tested for axial load) is not explicitly provided in this summary but would be detailed in the full test reports. Data provenance is not applicable here as it refers to physical and biological testing of manufactured products, not patient data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
Not applicable. This is a submission for physical medical devices and their connectors, not an AI/ML diagnostic or prognostic device that relies on expert interpretation of data for ground truth.
4. Adjudication Method for the Test Set
Not applicable. The "test set" here refers to physical product testing against international standards, not a diagnostic or classification task requiring expert adjudication.
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 not an AI-assisted diagnostic or imaging device.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not applicable. This is not an AI/ML algorithm.
7. The Type of Ground Truth Used
The "ground truth" for this device's performance is established by objective measurements and assessments against recognized international and national standards (e.g., ISO 80369-6, ISO 11607, ISO 11135, ISO 10993 series, ANSI/AAMI ST72, USP 788) for functional performance, sterility, packaging, and biocompatibility.
8. The Sample Size for the Training Set
Not applicable. This is not an AI/ML algorithm that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable. This is not an AI/ML algorithm.
