¹Mean station scores were adjusted for type of student, teaching site, preceptor group, OSCE day, and OSCE year. Only the teaching site variable is shown here.

Linear regression models were calculated for total OSCE scores, and MANOVA models were calculated for the station scores. ² Internal consistency was measured by the Kuder-Richardson-20 coefficient. ³ Reference Site I, N=84 students ⁴Denotes largest difference of adjusted site mean (in bold font) from reference constant. ⁵The reference constant comprises reference values for all predictor variables. ^* Means with asterisks are significant at p <= 001.
