The provided document is a 510(k) summary for the Meril Healthcare Pvt. Ltd. Latitud™ Hip Replacement System. This document focuses on demonstrating substantial equivalence to a predicate device, rather than providing a detailed study proving the device meets specific acceptance criteria in a clinical context.

The document primarily describes non-clinical performance data and biocompatibility testing to support the substantial equivalence claim. It does not include a multi-reader multi-case (MRMC) comparative effectiveness study, standalone algorithm performance, or details on ground truth establishment for a training set in the context of an AI/ML device. This is because the Latitud™ Hip Replacement System is a physical medical device (hip implant), not an AI/ML diagnostic or therapeutic system.

Therefore, many of the requested categories are not applicable to the content of this 510(k) summary. I will answer the applicable questions based on the provided text.

The provided text is a 510(k) Summary for the Latitud™ Hip Replacement System. This document focuses on demonstrating substantial equivalence to predicate devices based on design, materials, and mechanical performance testing, rather than presenting a clinical study with acceptance criteria and device performance as one might find for a novel diagnostic or therapeutic device.

Therefore, the requested information elements related to clinical study design (sample size, data provenance, expert ground truth, adjudication, MRMC studies, standalone performance, training set details) are not applicable to this type of submission.

However, I can extract information related to the non-clinical performance data and the conclusion on substantial equivalence.

Here's the relevant information that can be extracted:

Acceptance Criteria and Reported Device Performance

The acceptance criteria are generally established by the referenced ASTM and ISO standards for mechanical testing of orthopedic implants. The document states that the system "was subjected to following nonclinical performance testing to evaluate device function/mechanical performance." The implication is that the device met the requirements of these standards. Specific numerical acceptance criteria and precise performance values are not detailed in this summary; rather, the successful completion of these tests serves as the proof of meeting criteria for substantial equivalence.

1. A table of acceptance criteria and the reported device performance
See table above. The "reported device performance" is implied by the statement "subjected to following nonclinical performance testing to evaluate device function/mechanical performance" and the overall conclusion of substantial equivalence. For 510(k) submissions based on mechanical testing, specific numerical results are often contained in the full submission, but the summary confirms successful completion against established standards.

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

• Sample Size for Test Set: Not specified in the summary document. Mechanical testing for these types of devices typically involves a specified number of samples per test condition as dictated by the respective ASTM/ISO standards.
• Data Provenance: Not explicitly stated as "country of origin of the data." The applicant is Meril Healthcare Private Limited, based in Gujarat, INDIA. The testing was non-clinical (laboratory/mechanical testing), not human data.
• Retrospective or Prospective: Not applicable, as this is non-clinical performance data (material and mechanical testing).

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 510(k) for an orthopedic implant, where "ground truth" is established by adherence to recognized mechanical and materials testing standards, not by expert medical interpretation of clinical data.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. This describes non-clinical testing, not a clinical study requiring adjudication of expert opinions.

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 a 510(k) for an orthopedic implant, not an AI or imaging diagnostic device.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a 510(k) for an orthopedic implant.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for this submission are the established specifications and performance requirements outlined in the referenced ASTM and ISO consensus standards for orthopedic implants. Successful demonstration of meeting these standards through mechanical and material testing serves as the basis for substantial equivalence.

8. The sample size for the training set
Not applicable. This is a 510(k) for an orthopedic implant based on non-clinical performance and substantial equivalence to predicate devices, 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. See point 8.
