Model 5 (poor SP uptake): No doses received (coded as 1) versus 1 + doses (coded as 0). Model 6 (best SP uptake): 3 + doses (coded as 1) versus < 3 doses (coded as 0) (N = 317)
Odds ratios (OR) and 95% confidence intervals (CI) from general estimating equations for logistic regression. p < 0.05 bolded. ref reference group, CI confidence interval. Intercepts were included (not shown)
