What Are the Eligibility Criteria?

I think my guess is that because this had gone live, it did capture more bots than it did real individuals. It's possible that among the 619 there were some real people who were too busy to respond or dealing with their illness and not able to respond. But I figured if I really wanted to make sure that this data was trustworthy, I felt like I had to just scrap the 619 and start over after having put more rigorous eligibility screening criteria in place.
