I apologize, but the provided text from the FDA 510(k) clearance letter for the Alphatec Spine Proximity™ Anterior Cervical Plate System does not contain any information regarding acceptance criteria or a study that proves the device meets those criteria for software-based AI/ML devices.

The document details:

• Device Type: Spinal Intervertebral Body Fixation Orthosis (a physical implantable device, not a software/AI device).
• Regulations: Primarily related to medical devices, specifically orthopedic implants.
• Performance Data: Lists non-clinical (mechanical) testing based on ASTM standards (e.g., Static and Dynamic Compression Bending, Static Screw Push-out) and sterilization/packaging validations.
• Substantial Equivalence: Compares the mechanical design and indications for use of the Proximity™ system to predicate physical spinal fixation devices.

Therefore, I cannot extract the information required by your prompts (acceptance criteria table, sample sizes for AI test/training sets, expert ground truth establishment, MRMC studies, standalone performance, etc.) because these concepts are not applicable to the type of device described in this 510(k) clearance letter.

Not applicable. The "ground truth" here is adherence to mechanical performance standards, not expert clinical interpretation.

4. Adjudication Method for the Test Set

Not applicable. Adjudication methods like 2+1 or 3+1 are used for clinical studies involving reader agreement. This describes non-clinical mechanical testing.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• Was an MRMC study done? No. The document describes non-clinical mechanical tests for a spinal implant, not an AI/imaging device requiring human-in-the-loop evaluation.
• Effect size of human readers with AI vs without AI assistance: Not applicable.

6. Standalone (Algorithm Only) Performance Study

Not applicable. This device is a physical spinal implant, not an algorithm or AI software. Therefore, there is no standalone algorithm performance.
