^aPercentage weighted to reflect all eligible participants. Before COVID group sample size = 1200, weighted = 2273.80
^bAfter COVID group sample size = 1000, weighted = 2192.88
^cF statistics based on Wald Chi-square test statistics
^dPropensity score summarize difference in observable characteristics between before COVID group and after COVID group (i.e., age, income, education, etc.)
