MammoGRIP aids in positioning during radiologic visualization of the breast.

MammoGRIP™ is a non-medicated, 0.1% benzalkonium chloride foam solution intended to be used during mammography to facilitate breast positioning. When MammoGRIP is applied to the technician's hands, it imparts a slightly tacky or sticky surface while it is still damp, thereby allowing the technician to have a better grip of the dry breast tissue for optimal positioning in the field of view of the mammography machine. MammoGRIP is intended to be used with standard mammogram positioning techniques.

The provided text is a 510(k) summary for the MammoGRIP device. It does not describe a study involving an AI algorithm or its performance. Instead, it describes a device that aids in breast positioning during mammography by making a technician's hands slightly tacky. The acceptance criteria and "study" mentioned refer to biocompatibility tests and verification of physical characteristics for this accessory, not an AI performance study.

Therefore, most of the requested information regarding AI device performance, sample sizes, ground truth establishment, expert adjudication, and MRMC studies is not applicable to this document.

Here's what can be extracted based on the provided text, interpreted in the context of the device:

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample size used for the test set and the data provenance
The text describes biocompatibility tests (assays) and quality control verifications for the physical characteristics of the device. These are not "test sets" in the context of clinical performance data for an AI system. The sample size for these tests is not specified in the document, nor is the data provenance in terms of country of origin or retrospective/prospective nature, as these are typically laboratory tests.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This information is not applicable. The "ground truth" here would relate to the outcome of biological responses to the material (biocompatibility) or the physical/chemical properties of the product. These are assessed by laboratory procedures, not by expert interpretation of clinical data in the way an AI would be evaluated.

4. Adjudication method for the test set
Not applicable. Adjudication methods like "2+1" are used for expert consensus on clinical findings. For biocompatibility tests, results are typically determined by standardized laboratory protocols.

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
No. This is not an AI device, and no MRMC study was conducted or is relevant for this type of accessory.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
No. This is not an AI algorithm.

7. The type of ground truth used
For biocompatibility, the ground truth is established by the biological response observed in standardized assays. For physical characteristics, the ground truth is the measured physicochemical properties of the formulation.

8. The sample size for the training set
Not applicable. This is not an AI device that requires a training set.

9. How the ground truth for the training set was established
Not applicable. This is not an AI device.
