Question
We are performing a study on COVID 19 rates and are unsure if self-report of covid 19 diagnosis is a reliable measure to use
to capture diagnoses in the past 2 months. To answer this question, we surveyed a subsample of our study participants to
assess if self-report of receiving a covid 19 diagnosis from a health professional can be used as a proxy for estimating covid 19
diagnosis in our study population. We accessed the electronic health records of our study participants to verify their self-report
of COVID 19 diagnosis for the past 2 months.
Report all values as a percentage to 2 decimal places.
