The BC100 Body Composition Analysis System is a noninvasive bioimpedance analyzer for use in healthy subjects for measurement of actual height, actual weight and estimated body fat percentage. The applicable age range is 10 to 80 years old.

The proposed Athletic IQ, Inc. (AIQ) BC100 Body Composition Analysis System is a noninvasive bioimpedance analyzer for use in healthy subjects for measurement of actual height, actual weight and estimated body fat percentage. The applicable age range is 10 to 80 years old. The device determines estimated body fat percentage based on bioelectrical impedance analysis (BIA). BIA relies on the differing behavior of biological tissues in response to an applied electrical current. Lean tissue is generally highly conductive, whereas fat tissue and bone are relatively poor conductors. By analyzing the response to electrical signals, BIA permits differentiation of fat vs. lean tissue. When combined with the subject's height and weight parameters, age, and gender, an estimated body fat percentage may be calculated using an experimentally derived algorithm.

The provided text states that "Clinical testing was conducted to establish the algorithm used by the BC100 system for estimation of percent body fat using bioelectrical impedance data." However, it does not provide details on the acceptance criteria, the specific study design, or the results of this clinical testing. Therefore, I cannot construct the requested tables or provide detailed answers to many of your questions based only on the provided text.

Here's what can be extracted and what is missing:

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

• Acceptance Criteria: Not specified in the provided text.
• Reported Device Performance: Not specified in the provided text, beyond the general statement that "Clinical testing was conducted to establish the algorithm."

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 (Test Set): Not specified.
• Data Provenance: Not specified (country of origin, retrospective/prospective).

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 specified.

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

• Not specified.

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/Not specified. This device is a diagnostic tool, not an AI-assisted interpretation tool for human readers. It directly provides an estimated body fat percentage.

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

• Yes, implicitly. The device "determines estimated body fat percentage based on bioelectrical impedance analysis (BIA)" and calculates it "using an experimentally derived algorithm." This indicates a standalone algorithm performance without human intervention in the result generation. However, the performance metrics for this standalone algorithm are not provided.

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

• Not specified. For body fat analysis, a common ground truth method would be DEXA (Dual-energy X-ray absorptiometry) or hydrostatic weighing, but the text does not mention the method used.

8. The sample size for the training set

• Not specified. The text mentions "an experimentally derived algorithm," implying a training set was used, but no details are given.

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

• Not specified.

Summary of what is known from the provided text:

Crucially, the provided 510(k) summary and FDA letter do not contain the detailed clinical study results, acceptance criteria, or sample sizes that would allow for a comprehensive answer to your request. These details are typically found in the full 510(k) submission, not necessarily in the summary or clearance letter.
