Hi Team, For our analysis we are trying to link the data from the Respiratory Viral Results table with the Followup Survey A table. We want to know when a test was done to find the corresponding Survey A events. We looked at the "assay_datetime" column of the Respiratory Viral Results table but for a lot of patients it doesn't match with a survey A "timestamp". Do you know why ? Can we trust the "assay_datetime" from Respiratory Viral Results table. And otherwise do you have a recommendation to find the Survey A events corresponding the date of the test ? Thank you in advance for your feedback, Kind regards, Oscar Mallet
