These questions are generally addressed during the pre-sub for each FDA submission but I agree that the demographic information could be pretty infinite. I'm working on at least 5 of these AI submissions per week.
For example, lets say you have an AI submission for identifying cardiac ultrasound images. FDA will ask for very specific demographic information in the training and performance tests, as well as comorbidities (such as hypertension) for each training image. In addition, they will want at least three physicians to annotate the images. The training dataset is likely to contain at least 100-200K images.
Just my opinion as someone who has worked on many infusion pumps; that FDA review division is the best at FDA. They probably ask more cybersecurity questions than any other group I've encountered.
I review a minimum of 5x - 510ks a week.
One of my biggest mistakes was tuning a loop during the winter shutdown on a large scale vaccine reactor. It dramatically increased the cells growth rate to a point where we would have had to modify our drug application. Understandably, the regulatory people had me de-tune the loop.
