2. Sample Size Used for the Test Set and the Data Provenance:
The document does not explicitly state the specific sample sizes used for each test (e.g., freedom from holes, physical properties, biocompatibility) or their data provenance (country of origin, retrospective/prospective). However, for tests like "Freedom from Holes (D 5151)," it mentions an "AQL 2.5 Inspection Level G-1," which implies a statistically defined sampling plan as per ASTM D5151-06. The standard for biocompatibility tests (ISO 10993-10) also specifies testing guidelines.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts:
This information is not provided in the document. The document describes non-clinical tests (physical properties, biocompatibility) of a medical examination glove, which typically rely on standardized testing protocols rather than expert consensus on a test set (as would be the case for AI/imaging devices).
4. Adjudication Method for the Test Set:
This information is not applicable and therefore not provided in the document. Adjudication methods (like 2+1, 3+1) are common in studies involving human interpretation or subjective assessments, particularly in AI models for medical imaging. The tests described here are objective, quantitative measurements of material properties and biological responses.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done:
No, an MRMC comparative effectiveness study was not conducted. This type of study is relevant for AI-powered diagnostic or interpretive tools to assess how human readers' performance changes with AI assistance. The device in question is a physical glove, not an AI diagnostic tool.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:
No, a standalone study as defined for AI algorithms was not done. The device is a physical product, and its performance is evaluated based on its material properties and safety characteristics, not an algorithm's output.
7. The Type of Ground Truth Used:
The "ground truth" for the tests described are objective physical and chemical measurements and biological responses as defined by specific ASTM and ISO standards. For example:
- Freedom from Holes: Defined by the ASTM D5151-06 standard and its specified AQL (Acceptance Quality Limit).
- Tensile Strength & Ultimate Elongation: Measured according to material testing standards.
- Residual Powder: Measured according to ASTM D6124.
- Biocompatibility (Primary Skin Irritation, Dermal Sensitization): Determined by standardized animal or in-vitro tests following ISO 10993-10:2010 (E) protocols. The outcomes (e.g., "not a primary skin irritant") serve as the ground truth based on the established biological criteria of these tests.
8. The Sample Size for the Training Set:
This concept is not applicable to this device. A "training set" is used for machine learning algorithms. This device is a physical glove, not an AI model, and therefore does not have a training set.
9. How the Ground Truth for the Training Set Was Established:
This information is not applicable as there is no training set for this device.
