Thank you very much for the question.
The first cycle of the survey is now complete, as you mentioned. The results of this survey will be released this summer, so we'll start to have very good information that comes out. The second cycle is already under way. I think that longitudinal sense of how things are moving over time will also be very important for us.
We have started to see some of the initial findings on lead. For example, some of the data that's been talked about today were some of the early findings from those studies. We will be releasing the findings with more of the analysis this summer. We think there's a good opportunity to continue to put this information in the public domain and, as we say, to continue to monitor. We think the trends over time will be very important.
