- Data Provenance (Confirmatory Study 1): Retrospective, USA and EU.
- Test Set Sample Size (Confirmatory Study 2): 24 EU patients.
- Data Provenance (Confirmatory Study 2): Retrospective, EU.

3. Number of Experts and Qualifications for Ground Truth

Auto Abdominal Color Assistant 2.0: Not explicitly stated, but implies multiple "readers" to ground truth anatomical visibility. No specific qualifications are mentioned beyond "readers."
Auto Aorta Measure Assistant: Not explicitly stated, but implies multiple "readers" for measurements and an "arbitrator" to select the most accurate measurement. No specific qualifications are mentioned beyond "readers" and "arbitrator."
Auto Common Bile Duct (CBD) Measure Assistant: Not explicitly stated, but implies multiple "readers" for measurements and an "arbitrator" to select the most accurate measurement. No specific qualifications are mentioned beyond "readers" and "arbitrator."
Ultrasound Guided Fat Fraction (UGFF): Ground truth for the primary study was MRI Proton Density Fat Fraction (MRI-PDFF %). No human experts were involved in establishing the ground truth for UGFF, as it relies on MRI-PDFF as the reference. The correlation between UGFF and UDFF also used UDFF as a reference, not human experts.

4. Adjudication Method for the Test Set

Auto Abdominal Color Assistant 2.0: Not explicitly mentioned, however, the process described as "Readers to ground truth the 'anatomy' visible in static B-Mode image. (Before running AI)" and then comparing to AI predictions does not suggest an adjudication process for the ground truth generation itself beyond initial reader input. Confusion matrices were generated later.
Auto Aorta Measure Assistant: An "Arbitrator" was used to "select most accurate measurement among all readers" for the initial ground truth, which was then compared to AI baseline. This implies a 1 (arbitrator) + N (readers) adjudication method for measurement accuracy. For keystroke comparison, readers measured with and without AI.
Auto Common Bile Duct (CBD) Measure Assistant: An "Arbitrator" was used to "select most accurate measurement among all readers" for the initial ground truth, which was then compared to AI baseline. This implies a 1 (arbitrator) + N (readers) adjudication method for measurement accuracy. For keystroke comparison, readers measured with and without AI.
Ultrasound Guided Fat Fraction (UGFF): Ground truth was established by MRI-PDFF or comparison to UDFF. No human adjudication method was described for these.

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

Auto Aorta Measure Assistant: Yes, a comparative study was performed by comparing keystroke counts with and without AI assistance for human readers.
- Effect Size:
  - Long View Aorta AP Measurement: Average reduction from $4.132 \pm 0.291$ keystrokes (without AI) to $1.236 \pm 0.340$ keystrokes (with AI).
  - Short View Aorta AP and Trans Measurement: Average reduction from $7.05 \pm 0.158$ keystrokes (without AI) to $2.307 \pm 1.0678$ keystrokes (with AI).
Auto Common Bile Duct (CBD) Measure Assistant: Yes, a comparative study was performed by comparing keystroke counts with and without AI assistance for human readers.
- Effect Size: Average reduction of $1.62 \pm 0.375$ keystrokes (mean and standard deviation) from manual to AI-assisted measurements.
Other features (Auto Abdominal Color Assistant 2.0, UGFF): The documentation does not describe a MRMC study for improved human reader performance with AI assistance for these features.

6. Standalone (Algorithm Only) Performance Study

Auto Abdominal Color Assistant 2.0: Yes, the model's accuracy (detection accuracy, sensitivity, specificity, DICE score) was evaluated in a standalone manner against the human-annotated ground truth.
Ultrasound Guided Fat Fraction (UGFF): Yes, the correlation and agreement of the UGFF algorithm's values were tested directly against an established reference standard (MRI-PDFF) and another device's derived fat fraction (UDFF).

7. Type of Ground Truth Used

Auto Abdominal Color Assistant 2.0: Expert consensus/annotations on B-Mode images, followed by comparison to AI predictions.
Auto Aorta Measure Assistant: Expert consensus on measurements (human readers with arbitrator selection) and keystroke counts from these manual measurements and AI-assisted measurements.
Auto Common Bile Duct (CBD) Measure Assistant: Expert consensus on measurements (human readers with arbitrator selection) and keystroke counts from these manual measurements and AI-assisted measurements.
Ultrasound Guided Fat Fraction (UGFF): Established clinical reference standard: MRI Proton Density Fat Fraction (MRI-PDFF %). For one confirmatory study, another cleared device's derived fat fraction (UDFF) was used as a comparative reference.

8. Sample Size for the Training Set

The document states that "The exams used for test/training validation purpose are separated from the ones used during training process" but does not provide the sample size for the training set itself for any of the AI features.

9. How the Ground Truth for the Training Set was Established

The document implies that the ground truth for training data would have been established similarly to the test data ground truth (e.g., expert annotation for Auto Abdominal Color Assistant, expert measurements for Auto Aorta/CBD Measure Assistants). However, the specific methodology for the training set's ground truth establishment (e.g., number of experts, adjudication, qualifications) is not detailed in the provided text. It only explicitly states that "Before the process of data annotation, all information displayed on the device is removed and performed on information extracted purely from Ultrasound B-mode images" for annotation. Independence of test and training data by exam site origin or overall separation is mentioned, but not the process for creating the training set ground truth.

Summary discussion of the clinical tests submitted, referenced, or relied on for a determination of substantial equivalence.

UGFF Clinical Study: Acoustic property measurements including the Attenuation Coefficient (AC), Back scatter Coefficient (BSC), and Signal-to-Noise Ratio (SNR) were obtained from the liver of five hundred and eighty-two (582) participants in an external clinical study in Japan. The UGFF index is based on a least squares fit (estimation) between the acoustic property measurements and the corresponding MRI Proton Density Fat Fraction (MRI-PDFF %) measurements.

Table 1 summarizes baseline demographic information from the clinical study including sex, age, BMI, race, and ethnicity. There were no adverse effects or complications in the acquisition of the ultrasound clinical data.

Skin to Capsule Distance (SCD) [mm]	9.0 – 53.0

Strong correlation was confirmed between UFF values and MRI-PDFF. The correlation coefficient was 0.87. Bland-Altman analysis between UGFF and MRI-PDFF was conducted. The offset was -0.32% and the limit of agreement (LOA) was -6.0% to 5.4%. The differences between UFF and MRI-PDFF values were within ±8.4%, and results in 91.6% patients were smaller than the LOA.

A second confirmatory study was conducted on US and EU patients using the same least squares fit (estimation) to ensure performance was maintained on an independent dataset.

Table 2 summarizes the demographic information from the confirmatory study conducted on US and EU patients. Demographic information on the 5 EU patients was unavailable.

Table 2 Clinical patient data (US adults)

Sex
Male	5
Female	10
BMI	21.0 – 37.5
SCD [mm]	13.9 – 26.9

Strong correlation between UFF values and MRI-PDFF (correlation coefficient: 0.90) was also demonstrated in European and American populations. Bland-Altman analysis between UGFF and MRI-PDFF was conducted. The offset was -0.1%, and the limit of agreement (LOA) was -3.6% to 3.4%. The differences between UFF and MRI-PDFF values were within ±4.6%, and results in 95.0% patients were smaller than the LOA.

A third confirmatory study comparing UGFF with Ultrasound-Derived Fat Fraction (UDFF, Siemens) was conducted on 24 EU patients using the same least squares fit (estimation) to ensure performance was maintained on an independent dataset.

Strong correlation between UGFF and UDFF (correlation coefficient: 0.88) was also demonstrated. Bland-Altman analysis between UGFF and UDFF was conducted. The offset was -1.2%, and the limit of agreement (LOA) was -5.0% to 2.6%. The differences between UFF and MRI-PDFF values were within ±4.7%, and results in all patients were smaller than the LOA.

The results of the clinical study indicate that BMI, SCD, and other demographic confounders do not have a statistically significant effect on measurements of the AC, BSC, and SNR.
