Table 8 Multiple linear regression model with total UCAT score as the outcome and preparedness categories and demographic variables as covariates. The third and fourth columns show the multiple linear regression model with total UCAT score as the outcome and demographic variables as covariates using all included candidates (i.e. responders and non-responders) and does not therefore adjust for preparedness
