Notes: Income. aPatients who had multiple missed visits during each period are reported only once in this table. bPercentages are reported out of all patients with scheduled visits in a given time period. Evaluated percentage of all patients with scheduled visits who completed all visits within 7 days of the original scheduled date(s) (ie, no missed visits). Pre-COVID-19 time period is 1/1/2020-2/29/2020; COVID-19 is 3/16/20-5/31/20. cComparison of % missed visits between time periods (pre-COVID-19 versus COVID-19), based on chi-squared. dComparison of % missed visits vs % completed visits within COVID-19 time period, based on chi-squared.
