Logistic regression model of provider presentation of vaccine as elective or contraindicated*.

Variable	Risk Ratio	95% Confidence Interval	p-value
HPV Vaccine Presentation	3.82	1.68, 6.75	0.002
Child Sex (Female)	1.18	0.49, 2.63	0.704
Parent Sex (Female)	1.10	0.36, 2.93	0.854
Parent education (>High School)	0.74	0.29, 1.75	0.52

*The reference group is provider presentation for meningococcal vaccination for male children with a male parent with an education level of high school or less.

Interpretation: We estimated a logistic regression model of provider presentation of vaccine as elective or contraindicated vs. indicated on vaccine type, child sex, parent sex, and parent education. Model estimates were used to obtain risk ratios associated with each covariate. The risk ratio of 3.82 for HPV vaccination indicates that providers were 3.82 times more likely to present HPV vaccination as elective or contraindicated than meningococcal vaccination.
