  • Data Provenance: Not explicitly stated as retrospective or prospective, but collected from USA (41.2%), Austria (3.8%), Australia (1.1%), Japan (41.3%), Italy (0.7%), and Greece (12%).

3. Number of Experts and Qualifications for Ground Truth

• Auto Renal Measure Assistant:
  • Number of Experts: 2 "Readers" and 1 "Board Certified Nephrologist" for arbitration.
  • Qualifications: "certified sonographer/Clinician" for the two readers. "Board Certified Nephrologist" for the arbitrator.
• Auto Abdominal Color Assistant:
  • Number of Experts: Unspecified number of "Readers".
  • Qualifications: "certified sonographer/Clinician" for the readers.
• Auto Preset Assistant:
  • Number of Experts: Unspecified number of "Readers".
  • Qualifications: "certified sonographer/Clinician" for the readers.

4. Adjudication Method for Test Sets

• Auto Renal Measure Assistant:
  • Method: A "Board Certified Nephrologist arbitrated the ground truth between the above two readers to establish the reference standard". This implies a 2+1 (two readers, one arbitrator) method.
• Auto Abdominal Color Assistant & Auto Preset Assistant:
  • Method: The text states, "Readers (certified sonographer/Clinician) to ground truth the 'anatomy' visible in static B-Mode image." There is no mention of multiple readers or an arbitration process, implying no explicit inter-reader adjudication method was described beyond individual expert annotation.

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

• No MRMC comparative effectiveness study was explicitly described in the provided text. The studies focus on the standalone performance of the AI algorithms against a derived ground truth, rather than comparing human reader performance with and without AI assistance. Therefore, no effect size for human readers' improvement with AI assistance is reported.

6. Standalone (Algorithm Only) Performance Study

• Yes, standalone (algorithm only) performance studies were done for all three AI features listed. The studies evaluate the accuracy or success rate of the AI algorithms in performing their intended functions (measurement, view suggestion) against an established ground truth, without a human-in-the-loop component being explicitly tested or reported.

7. Type of Ground Truth Used

• Auto Renal Measure Assistant: Expert Consensus, as it involved two readers and an arbitrator to establish the reference standard for measurements.
• Auto Abdominal Color Assistant & Auto Preset Assistant: Expert Annotation/Consensus, established by "Readers (certified sonographer/Clinician) to ground truth the 'anatomy'visible in static B-Mode image." While not explicitly stated as consensus among multiple readers, it is established by qualified experts.

8. Sample Size for Training Sets

• The training set sample sizes are not explicitly provided in the summaries for any of the AI features. The document only mentions that the "verification data was acquired independently during validation process after the development of the model," and "The exams used for test/training validation purpose are separated from the ones used during training process." This implies training data existed but its size is not detailed.

9. How Ground Truth for Training Sets Was Established

• The document does not explicitly describe how the ground truth for the training sets was established. It focuses primarily on the process for the test/validation sets. However, it can be inferred that a similar process involving expert clinicians/sonographers would have been used to establish ground truth for training data, as is common practice in medical imaging AI development.
