Ordinal logistic regression testing the association between predictors and change in clinical research interest.

^aModel 2 controlled for campaign year in addition the listed variables.

^bSubjects watched the video from a peer-shared source vs a survey-shared source (ie, through a link provided on the postcampaign Career Orientation Survey).

^cSubjects were recruited by friends participating in the clinical research program vs friends participating in the field research program.

^dUnderrepresented minority in medicine characterized as Hispanic, Black, Pacific Islander, or Native American.
