All percentages are column percentages. Race and ethnicity were reported in a free-entry field; they do not add to 100% because patients could be identified with multiple racial and ethnic categories. P value from chi-square test of association between time period (pre-pandemic vs pandemic) and each variable. The distribution of quarterly counts were compared with a Wilcoxon test; we present the means and variances for reference, but the Wilcoxon test does not compare these.

IQR = interquartile range; CT = Connecticut; NJ = New Jersey; NY = New York; NYU = New York University.
