Extended Data Table 4 Regression-estimated effects of text reminders on appointments and vaccinations at UCLA Health in the second RCT

From: Behavioural nudges increase COVID-19 vaccinations

  1. Regression-estimated effects of receiving a text reminder (altogether or broken down by reminder type) on appointments and vaccinations at UCLA Health in the second RCT. The two outcome measures are whether participants scheduled an appointment to get the first dose of the COVID-19 vaccine at UCLA Health from 15:00 h on the second reminder date to 23:59 h on the fifth day following the second reminder date  (‘Appointment at UCLA (Within Six Days)’) and whether participants obtained the first dose of the COVID-19 vaccine at UCLA Health within four weeks of the second reminder date (‘Vaccinated at UCLA (Within Four Weeks)’). Supplementary Tables 14, 15 provide results of complete OLS regressions that are used to estimate the effects reported here. All P values are two-sided without multiple comparison adjustments. ‘N’ refers to the number of observations in each regression.
