The provided document describes a medical device (Tosama 100% Cotton Menstrual Tampon) and its substantial equivalence to predicate devices, rather than an AI-powered diagnostic tool. Therefore, many of the requested categories for acceptance criteria and study design (such as Number of experts used to establish the ground truth, Adjudication method, MRMC comparative effectiveness study, Standalone performance, Type of ground truth, and Sample size for the training set and Ground truth for training set) are not applicable.

However, I can extract information related to the device's performance, the tests conducted, and the basis for its equivalence.

Here's the information derived from the provided text, adapted to the closest relevant categories:

1. A table of acceptance criteria and the reported device performance

The document doesn't explicitly state "acceptance criteria" but lists various physical and functional specifications for the tampon, along with reported values for the Tosama 100% Cotton Menstrual Tampon and the predicate devices. The study objective was to demonstrate substantial equivalence, meaning the Tosama device performs within the same established ranges as the predicates.

The "study that proves the device meets the acceptance criteria" is described as a non-clinical data summary. This non-clinical data was used for substantial equivalence determination to predicate devices already on the market.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

• Sample Size: Not explicitly stated for each test, but it is implied that representative samples of the Tosama 100% Cotton Menstrual Tampon and its components were tested.
• Data Provenance: The manufacturer is TOSAMA, d.o.o. from Slovenia, EU. The testing appears to have been conducted by or for the manufacturer. The data is likely prospective, as it relates to testing the specific device for regulatory submission.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Not applicable. This is a physical and chemical testing study for a medical device, not an AI-powered diagnostic tool requiring expert ground truth for interpretation.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. This is a physical and chemical testing study, not based on human review/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 device.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is not an AI device. The device itself is a standalone medical product.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)

The "ground truth" in this context refers to established test methodologies and results for similar predicate devices, and the physical, chemical, and microbiological properties of the materials and finished product. Testing followed "recommended requirements."

• Chemical Analysis: Tests for pesticide, dioxin, heavy metal, phthalate, and PCB residues.
• Microbiological Testing: Enumeration per USP <61>/<62>, Toxic Shock Syndrome Toxin-1 production, vaginal microflora growth alteration, and S. aureus growth enhancement.
• Biocompatibility Testing: In vitro cytotoxicity, intracutaneous and vaginal irritation, sensitization, and acute systemic toxicity.
• Efficacy Testing: Syngina absorbency, fiber loss, withdrawal cord pull-out resistance, and tampon integrity.
• Physical Characteristics: Length, diameter, mass, withdrawal cord length, applicator dimensions.

8. The sample size for the training set

Not applicable. This is not an AI device, so there is no "training set."

9. How the ground truth for the training set was established

Not applicable. There is no training set as it is not an AI device.

Ask a specific question about this device

The Lil-lets tampons (both types) are unscented tampons for:
• Women's personal hygiene with respect to intra vaginal absorption of menstrual or other vaginal discharge.
• The plastic applicator is for easing the placement of the tampon correctly into the vagina (only the Lil-lets Silk Comfort Compact Plastic Applicator Tampon).

Lil-lets tampons are used to absorb menstrual fluid. Lil-lets series tampons come with a plastic applicator and without a plastic applicator in sizes: Lite, Regular, Super, Super plus and Ultra. Lil-lets tampons are made of commercial cotton and rayon, a polyethylene/polyester cover, and cotton or rayon string.

The provided 510(k) summary (K120481) for the Lil-lets Silk Comfort Compact Plastic Applicator Tampon & Lil-lets Non-Applicator Tampon describes pre-clinical testing to demonstrate substantial equivalence to a predicate device, MAXIM Plastic Applicator and Non Applicator Tampons (K080775). However, it does not contain a comprehensive study proving that the device meets specific acceptance criteria in the manner typically described for clinical studies of new medical devices with defined performance metrics, patient populations, and statistical analysis.

Instead, the summary focuses on non-clinical tests to ensure safety and equivalence based on existing standards and knowledge of the predicate device. The "acceptance criteria" are implied by adherence to these standards and by demonstrating that the Lil-lets tampons do not present new questions of safety or effectiveness.

Here's a breakdown of the information based on the provided text, using the requested format where applicable:

1. Table of Acceptance Criteria and Reported Device Performance

Detailed Study Information:

This document is a 510(k) summary focused on demonstrating substantial equivalence for tampons, not a report of a traditional clinical performance study for a novel device. Therefore, many of the requested points do not apply or are not explicitly detailed in the provided text, as the regulatory pathway chosen (510(k)) relies heavily on comparing technical and safety characteristics to a legally marketed predicate device.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

• The document does not specify general "test set" sample sizes or data provenance in the context of a clinical study.
• For Syngyna testing, it states "Syngyna testing was conducted," but does not provide the number of tampons tested. This is a bench test performed in a lab, not on human subjects.
• For Microbiology and Physical/Chemical tests, no sample sizes are provided for individual tests.
• Data provenance for these non-clinical tests would likely be the manufacturing site or a contract lab performing the tests, which is in Slovenia, given the submitter's address.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):

• Not applicable in this context. "Ground truth" in the sense of expert consensus for diagnostic performance is not relevant to non-clinical tests of tampon safety and absorbency. Expertise is implied by adherence to regulatory standards and testing methodologies by competent personnel.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

• Not applicable. This concept is for clinical studies involving human interpretation or challenging outcomes.

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 device is a tampon, not an AI-assisted diagnostic tool or an imaging device.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

• Not applicable. This device is a physical product (tampon), not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

• The "ground truth" for these non-clinical tests would be the established regulatory standards and validated test methodologies themselves (e.g., 21 CFR 801.430(f)(2) for absorbency, specific microbiological assays, internal physical testing protocols).
• For biocompatibility, the ground truth is the accepted safety profile of the predicate device's materials.

8. The sample size for the training set:

• Not applicable. There is no "training set" in the context of such a device and its regulatory submission.

9. How the ground truth for the training set was established:

• Not applicable.
