2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document does not specify the exact sample sizes used for each individual test (e.g., number of gloves tested for holes, tensile strength, etc.). The mention of "non clinical tests" suggests these are laboratory-based evaluations.

The data provenance is not explicitly stated in terms of country of origin. The testing for Glutaraldehyde Resistance was performed by "TRI/Environmental, Inc.", which is likely a US-based laboratory, but this is not definitively stated as the origin of all data. The study appears to be prospective in nature, as new glove samples would be manufactured and tested against predefined standards.

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)

This section is not applicable as the document describes the performance of a physical product (examination gloves) against established laboratory standards (ASTM standards and other performance metrics) rather than the interpretation of medical images or data requiring expert consensus or ground truth in the context of AI or diagnostics. The "ground truth" here is the physical measurement and chemical testing results according to the specified test methods.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This section is not applicable. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies or AI evaluations where multiple human readers review data and discrepancies need to be resolved. For laboratory testing of physical products, the results are derived directly from the test methodology, and repeatability/reproducibility are typically addressed within the standard itself.

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

This section is not applicable. This document describes the performance of a medical device (examination gloves) through laboratory testing, not an AI system. Therefore, no MRMC study or AI assistance evaluation was conducted.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This section is not applicable. This document describes the performance of a medical device (examination gloves), not an algorithm or AI system.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" for the performance of the Nitra-Touch™ examination gloves is based on:

  • Established ASTM Standards and Test Methods: These standards define specific procedures and criteria for evaluating properties like dimensions, physical properties (tensile strength, elongation), freedom from holes, and tensile strength (ASTM D 3578, ASTM D 5250, ASTM D 5151, ASTM D 120-87, ASTM T F739-91).
  • Laboratory Measurements and Chemical Analyses: The performance metrics (e.g., MPa for tensile strength, lbf/in for puncture resistance, breakthrough time for chemical resistance, mg residue by mass) are direct results of these standardized tests.
  • Biocompatibility Testing Protocols: "Passes" for Primary Skin Irritation and Guinea Pig Sensitization indicate adherence to established biological safety testing protocols for medical devices.

8. The sample size for the training set

This section is not applicable. There is no "training set" in the context of evaluating the performance of physical examination gloves. This concept applies to machine learning models, not physical product testing.

9. How the ground truth for the training set was established

This section is not applicable for the same reasons as point 8.

§ 880.6250 Non-powdered patient examination glove.

(a)
Identification. A non-powdered patient examination glove is a disposable device intended for medical purposes that is worn on the examiner's hand or finger to prevent contamination between patient and examiner. A non-powdered patient examination glove does not incorporate powder for purposes other than manufacturing. The final finished glove includes only residual powder from manufacturing.(b)
Classification. Class I (general controls). The device, when it is a finger cot, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 880.9.
