REGRESSION
Table Odds ratios and 95% CIs from regression of vaccine outcomes on treatments and covariatesNote: 95% CIs are reported in parentheses. The CIs are based on standard errors that are clustered at the village level. AIC, Akaike information criterion.The second set of models presents similar results for reported vaccine status that was obtained, 2 months after individuals were treated, either by telephone in phase II of the trial or by the phase III in-person follow-up. Reported vaccination status in phase II and phase III (model 3) was considerably lower than intention levels, hence the lower intercept term. In post-treatment, the odds of individuals in the cash treatment reporting having a COVID-19 vaccine were about 1.21 times greater than the odds for those in the placebo arm. For the model specification with both low and high cash treatments (model 4), low cash participants have 1.28 times the odds of those in placebo reporting a COVID-19 vaccination. The covariate controls have little effect on reported vaccinations; the exception is that respondents with denser social networks are more likely to report having received the vaccine.The final set of models in Table Extended Data Fig. Figure
