Clinician Specialty	No. of Visits of Adolescents		HPV Vaccination
	Total Office Visits	HPV Vaccine Administered	% Change	95% CI
Pediatrician	782,172	127,116	0.05b	0.04-0.07
Family physician	96,384	18,875	0.08b	0.06-0.09

CDC = Centers for Disease Control and Prevention; HPV = human papillomavirus vaccine.

^aIndependent variable was net incentives earned per dose, calculated as the difference between HPV vaccine cost reimbursement and the CDC list price. The dependent variable was the proportion of HPV vaccine visits (ie, the number of visits the HPV vaccine was administered divided by the total number of preventive care visits times 100). Linear regression models were constructed for each specialty adjusting for the proportion of visits by female and urban adolescents and weighted for the number of preventive care visits.

^bStatistically significant at P <0.05.
