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

The document describes material and performance testing, not a "test set" in the sense of an AI model's dataset. The "samples" refer to physical gloves selected for testing.

The provenance of the data is from laboratory testing conducted on the manufactured gloves. The specific country of origin for the testing itself is not explicitly stated, but the manufacturer is Shandong Maida Medical Technology Co.,Ltd. in China. The testing is prospective in the sense that newly manufactured gloves are tested to ensure they meet the standards.

• ASTM D5151 (Detection of Holes): Sample size for water leakage test: 125 gloves.
• ASTM D6319 (Dimensions & Physical Properties): Results are shown for multiple lots (e.g., Lot no.: 210515, 210518, 210520), indicating multiple samples were tested across different manufacturing batches. The exact number of gloves per lot for each physical test (e.g., tensile strength, elongation) is not specified but would be defined by the ASTM standard.
• ASTM D6978 (Chemotherapy Permeation): The results provide triplet values for Carmustine and Thio Tepa (e.g., 22.8(23.7, 22.8, 23.1)), suggesting three independent measurements were taken for these drugs. The standard itself specifies the number of replicates.
• Biocompatibility Testing: The number of animal subjects used for the animal irritation, sensitization, and systemic toxicity tests is not specified in the summary but would conform to the respective ISO standards.

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

This section is not applicable as the evaluation involves standardized laboratory testing against defined physical and chemical properties, not human expert interpretation of subjective data or images. The "ground truth" is defined by the objective measurement results according to the specified ASTM and ISO standards.

4. Adjudication Method for the Test Set

This is not applicable. Adjudication methods (like 2+1, 3+1) are for resolving discrepancies in human expert assessments (e.g., in medical image interpretation). Here, numerical test results from standardized methods are directly compared against established quantitative or qualitative acceptance criteria.

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

This is not applicable. MRMC studies are used to evaluate diagnostic imaging systems or AI tools where human readers are involved. This submission is for a physical medical glove.

6. Standalone (Algorithm Only) Performance

This is not applicable. This concept applies to AI/software performance. The device is a physical glove, not an algorithm.

7. Type of Ground Truth Used

The ground truth used is based on objective, quantitative measurements derived from standardized laboratory tests (bench testing) and biological responses observed in validated biocompatibility assays according to international standards (ASTM and ISO). This includes:

• Quantitative Thresholds: e.g., minimum tensile strength, maximum residual powder, minimum breakthrough time for chemotherapy drugs.
• Qualitative Observations (Biological): e.g., absence of irritation or sensitization, absence of systemic toxicity.
• Conformity to Standards: The device's performance is compared directly to the specified requirements within each standard (e.g., ASTM D6319-19 dimensions, physical properties).

One point of note is the cytotoxicity result (17.1% viability) which is below the 70% threshold, indicating cytotoxicity. The document addresses this by stating: "Analysis3: The proposed device is potentially cytotoxic, but all proposed devices are conducted the systemic toxicity test." And the systemic toxicity test showed "no evidence of systemic toxicity." This implies that despite the in vitro cytotoxicity, the manufacturer argues that in vivo systemic toxicity (which is generally considered a more critical endpoint for patient safety) was not observed, suggesting the findings are acceptable for the device's intended use according to the biocompatibility evaluation framework.

8. Sample Size for the Training Set

This is not applicable. There is no "training set" in the context of a physical device. The manufacturing process is controlled to produce gloves consistently, and batch testing ensures quality.

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

This is not applicable. As there is no training set, the establishment of ground truth for it is irrelevant. The manufacturing process is designed and verified to produce products meeting the specified design and performance criteria.
