The "study that proves the device meets the acceptance criteria" is described as "Non clinical tests were conducted to verify that the proposed device met all design specifications as was Substantially Equivalent (SE) to the predicate device." (page 5, "7.0 _Non-Clinical Test Conclusion"). These tests demonstrated compliance with the listed ISO and IEC standards.
2. Sample size used for the test set and the data provenance
The document does not specify a "test set" in the context of data or AI model evaluation. The tests conducted were non-clinical performance and safety tests of the physical wheelchair device. The provenance of the data is not applicable in this context as it refers to physical testing results against engineering standards.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. This is not an AI device or a diagnostic device where expert ground truth would be established for image or data interpretation. The "ground truth" here is the pass/fail criteria defined by the ISO and IEC standards.
4. Adjudication method for the test set
Not applicable, as there is no human adjudication of a test set in the context of this device's non-clinical safety and performance testing.
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-assisted diagnostic or interpretation device. No MRMC study was performed or is relevant to this submission.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an algorithm or AI device.
7. The type of ground truth used
The "ground truth" for the device's performance is adherence to the specifications and performance metrics outlined in the various international standards (ISO and IEC) for wheelchairs and medical devices. These standards define the acceptable range or criteria for parameters like static stability, dynamic stability, braking effectiveness, energy consumption, dimensions, maximum speed, strength, climatic performance, obstacle climbing, power/control systems, electromagnetic compatibility, battery safety, and biocompatibility.
8. The sample size for the training set
Not applicable, as this is not an AI device that requires a training set.
9. How the ground truth for the training set was established
Not applicable, as this is not an AI device that requires a training set or ground truth establishment for AI models.

The biocompatibility of the Predicate device and Subject device meet the requirements of the ISO 10993-5:2009 & ISO 10993-10:2010. The flame retardant test of the seat cushion/back cushion and armrest of both subject device and predicate device is carried out according to the ISO 7176-16 test. Therefore, both devices are assured to be under the same safety level. In conclusion, the technological characteristics, features, specifications, materials, mode of operation, and intended use of the device substantially equivalent to the predicate devices quoted above. The differences between the subject device and predicate devices do not raise new issues of safety or effectiveness. The differences between the subject device and predicate devices do not raise new issues of safety or effectiveness.
10.0 Conclusion
The conclusions drawn from the comparison and analysis above demonstrate that the proposed device is as safe, as effective, and performs as well as the legally marketed predicated device and raises no new questions of safety or effectiveness. The differences between both devices are insignificant in terms of safety and effectiveness.
