Summary of final logistic regression model for accuracy^a

Variable	Estimate (β)	SE	z value	p value	Odds ratio
Intercept	−1.107	0.164	−6.746	<0.001	0.33
Course work	0.684	0.192	3.572	<0.001	1.98
Years in College	0.188	0.094	1.981	0.048	1.21

^an = 511. Bolded values are significantly different from 0 (p < 0.05). This final model is a product of a model selection process that finds the most significant variables. Initially included variables were “Course work” (whether the student self-reported taking course work addressing vaccines), “Confidence” (whether the student reported being confident in their vaccine knowledge), “Gender,” “First-Generation” (college-going status), “Race/Ethnicity” (reference level is white race), “Expertise Level” (NPH, PH, or EBM status), and “Years in College” (linear variable, “freshman” designated as 0 years).
