Extended Data Table 1 Randomization Check of the RCTs
From: Field testing the transferability of behavioural science knowledge on promoting vaccinations
- This table compares participant demographics across message conditions within each RCT (Panels A-C) as well as between the message conditions combined and the aggregate holdout condition (Panel D). The variables reported here include whether a participant that was initially enrolled in the RCTs met the eligibility criteria to be included in our final analysis sample; participant age; whether a participant was a man (versus a woman, other or unknown); and whether a participant’s race/ethnicity on their medical record was White, Black, Asian, other races, unknown, or Hispanic/Latino. For age, gender, and race/ethnicity variables, this table only reports information about patients included in the analysis sample. For whether patients were retained in the analysis, patient age, and whether patients were male, we predicted each variable using OLS regressions as a function of indicators for the relevant conditions under comparison in each panel, with robust standard errors to correct for heterogeneity. A two-sided F-test was conducted for each regression to compare the overall significance of differences across relevant conditions for a given variable. To summarize across all categories of race/ethnicity, we ran a chi-squared test to assess whether there was any association between randomly assigned conditions in each panel and race/ethnicity.
