Abstract: Third, we are worried that COVID-19 vaccination might be a potential confounder.In this study, COVID-19-related outcomes were detected between March 2020 and March 2021.However, we discovered that the US COVID-19 vaccination program started on December 14, 2020, and those who were susceptible to COVID-19 hospitalization and death were given priority for COVID-19 vaccines.4 Until March 1, 2021, the cumulative coverage of COVID-19 vaccination among adults in the US was approximately 20%. 4 Therefore, owing to the high rate of COVID-19 vaccination, we suggest the reception of COVID-19 vaccine be considered in this study.In conclusion, we believe that more considerations about selection bias, case ascertainment, and residual confounders could enhance the accuracy and impact of the study.
