2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample sizes used for each specific test (e.g., how many gloves were tested for length or tensile strength). However, the tests are conducted according to ASTM D3578-19, ASTM D5151-19, ASTM D6124-06, and ASTM D5712-15, which describe the standard test methods and typically include specifications for sampling.
The data provenance is from non-clinical bench testing and biocompatibility studies of the "Comfortpro" device. The manufacturer is THAI RUBBER INDUSTRY COMPANY LIMITED, located in Thailand. The tests are therefore likely performed by the manufacturer or a third-party lab on behalf of the manufacturer, and the data is prospective as it's generated specifically for this 510(k) submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This type of device (patient examination glove) does not involve a "ground truth" established by human experts in the typical sense of medical image analysis or diagnostic studies. The performance is assessed against established international consensus standards (ASTM and ISO) for physical properties and biocompatibility. The "ground truth" is not based on expert interpretation but on the quantitative measurement and qualitative assessment defined by these standards.
4. Adjudication Method for the Test Set
Not applicable. As noted above, the performance is measured against objective standards, not subjective human assessment requiring 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-powered diagnostic device or a device where human interpretation is a primary performance factor.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This is a physical medical device (glove), not an algorithm or AI system.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" in this context is defined by international consensus standards (ASTM D3578-19, ASTM D5151-19, ASTM D6124-06, ASTM D5712-15, ISO 10993-10:2010(E), ISO 10993-5:2009(E), ISO 10993-11:2017(E)). These standards specify the test methods and the acceptable ranges for the physical and biological properties of the gloves.
8. The Sample Size for the Training Set
Not applicable. This is not a machine learning or AI device that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable. There is no training set for this type of device.
