Bivariate and multivariate log-binomial regression models the risk of FIT non-return. Multivariate model includes all variables in the table. Risk ratios greater than one indicate the patient characteristic is a risk factor for failing to return the FIT and risk ratios less than one indicate a beneficial characteristic for FIT return. Bold font indicates statistical significance at the two-sided α = 0.05 level.
