Visit & Initial Test

Hi, Is there any record in visit_occurrence table for a patient where visit date is the date of the initial test?

Hi @egealpay , when I curated the dataset for Q2, I set the cut-off date as the COVID measurement date and keep data that has time smaller or equal to the measurement date. So there will be visits that are on the same date as the initial COVID tests. Thanks, Yao
Is this also holds for the data of question 2?
Hi @egealpay, No, when we filter out records occurring after the initial test date, we use `less than` not `less than or equal to`, so none of the records should have the same date as the initial test. Thanks, @trberg
