This is the engineer in me, so I'll say sorry in advance, but were you able to correlate any of the contributing factors—for example, drinking water? We know that there are more boil water advisories now than there were two years ago. That should have an effect on oral health. Are you able to see anything like that from your audits, or is that not part of the scope?
