Table 3.
Ratio of monthly enrollment of subjects per students versus nurses adjusted for key covariates.* Values shown are rate ratios (RR) with 95% CI. Baseline categories are identified for each categorical covariate.

RR: Rate Ratio which is the frequency of enrollment occurring by month over the duration of enrollers participating in the study;
