^*Education, Donation type, and donor type were not included in the analyses of HIV deferral and Leave without Donation as covariates because such information was not available for a substantial number of deferred donors. Pamphlet by education interaction was tested but not significant in the models for CUE use and positive marker rates, therefore it was removed from the final models.
