Not Found
I am sorry, but the provided text does not contain the information required to answer your request. The document is an FDA 510(k) clearance letter for "Allwin Dilator & Sets", which specifies the device's indications for use and regulatory information. However, it does not describe any acceptance criteria or a study that proves the device meets specific performance criteria through a rigorous testing process involving AI or human reader performance.
Therefore, I cannot provide:
- A table of acceptance criteria and reported device performance.
- Sample size used for the test set or data provenance.
- Number of experts or their qualifications.
- Adjudication method for the test set.
- Information about a multi-reader multi-case (MRMC) comparative effectiveness study or effect size.
- Information about standalone (algorithm only) performance.
- The type of ground truth used.
- The sample size for the training set.
- How the ground truth for the training set was established.
This document is a regulatory approval letter for a medical device (dilators and sets), not a technical report or study detailing the validation or performance of an AI/ML diagnostic tool.

Dear Digish Mehta:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
