The device can be operated indoors, or outdoors on dry, level surfaces composed of concrete, blacktop, or asphalt under normal driving conditions.

The provided FDA 510(k) summary is for a Manual Wheelchair (MW18), a Class I, reserved medical device. This type of device does not typically involve AI components or require the complex statistical studies, multi-reader multi-case studies, and expert ground truth establishment that are common for AI/ML-driven diagnostic devices.

Instead, the acceptance criteria for a manual wheelchair primarily focus on functional performance, safety, and compliance with established industry standards. The study proving the device meets these criteria is a series of non-clinical performance tests conducted in accordance with international standards for wheelchairs.

Here's the breakdown of the information requested, based on the provided document:

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

The document lists the ISO standards that the device complies with, which effectively serve as the acceptance criteria. The "reported device performance" is the statement of compliance with these 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 patient data, as this is a mechanical device. The "test set" refers to the physical units of the Manual Wheelchair (MW18) that were subjected to the non-clinical tests. The document does not explicitly state the number of sample units used for these tests. Data provenance is not applicable in the context of patient data as it's not an AI/ML device.

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 to this device. "Ground truth" in the context of AI/ML performance is not relevant for a mechanical manual wheelchair. The "truth" is established by the ability of the device to meet the defined performance specifications and safety standards through physical testing.

4. Adjudication method for the test set

This information is not applicable. Adjudication methods like 2+1 or 3+1 are typically used for establishing ground truth in clinical image interpretation, not for mechanical device testing. Compliance with standards is typically assessed by conformity to predefined pass/fail criteria for each test.

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

This is not applicable. An MRMC study is designed for evaluating the performance of diagnostic algorithms, often with human readers in the loop. This device is a manual wheelchair, not a diagnostic AI tool.

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

This is not applicable. This is a mechanical device, not an algorithm.

7. The type of ground truth used

The "ground truth" for this device is the compliance with established international performance and safety standards (ISO standards) for manual wheelchairs. This is determined through objective, quantifiable physical tests, rather than expert consensus, pathology, or outcomes data in the way it's understood for diagnostic devices.

8. The sample size for the training set

This is not applicable. There is no "training set" for a mechanical device like a manual wheelchair.

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

The A006 Manual Wheelchair is to provide mobility to persons limited to a sitting position.

The subject device is a mechanical wheelchair which is a manually operated device with wheels that is intended for medical purposes to provide mobility to persons restricted to a sitting position. It can be folded for transport by bringing the two sides together. The manual wheelchair incorporates a main frame, a seat, two adjustable footrests and four wheels. The larger rear wheels have hand rims of slightly smaller diameter projecting just beyond the tire. These allows the user to maneuver the chair by pushing them on without requiring them to grasp the tires. The manual wheelchairs have brakes that bear on the tires of the rear wheels and two push handles at the upper rear of the frame to allow for manual propulsion by an assistant.

This document describes the FDA's clearance of a Manual Wheelchair (Model A006) and is a 510(k) Premarket Notification. The purpose of a 510(k) submission is to demonstrate that a new device is "substantially equivalent" to a legally marketed predicate device. This process differs significantly from studies that prove a medical device, especially AI/ML-driven software, meets specific performance acceptance criteria through clinical or non-clinical trials.

Therefore, the provided text does not contain the information required to answer the prompt. It is a regulatory clearance document for a mechanical device, not a study evaluating the performance of an AI/ML device against acceptance criteria.

Here's why the prompt cannot be answered with this document:

• No AI/ML device: The device in question is a manual wheelchair, a physical, mechanical product. There is no software, AI, or algorithm involved.
• No "acceptance criteria" in the AI/ML performance sense: The "acceptance criteria" here refer to meeting regulatory standards for safety and effectiveness in comparison to a predicate mechanical device (another wheelchair), not to the performance metrics (like accuracy, sensitivity, specificity, AUC) typically established for AI/ML devices.
• No "study" in the AI/ML performance sense: The document describes non-clinical performance testing against established ISO standards for wheelchairs (e.g., static stability, brake effectiveness, dimensions, strength). It explicitly states, "No clinical study is included in this submission." There are no human readers, ground truth establishment, training sets, test sets, or MRMC studies as would be relevant for an AI/ML device.

To answer the prompt, a document describing the development and validation of an AI/ML-driven medical device, including performance data from a clinical or non-clinical study, would be necessary.
