Output from the multivariable logistic regression model of case-control interviews, with clinical scenario 2 (likely chronic infection) as the dependent variable *.

Variable	Odds Ratio (OR)	95% CI	p Value
Received a blood transfusion (ever)	3.26	1.74–6.11	0.0002
Lived with someone who had hepatitis (any)	12.46	5.18–29.97	<0.0001
High-risk ethnic origin 1	8.39	5.91–11.91	<0.0001

¹ Ethnic origins from highly endemic HBV countries (>5% prevalence). People of African, Asian (East, Southeast, West, and South, unspecified), Chinese, and Filipino ethnic origin have an increased likelihood of having been born in or having lived with people born in HBV-endemic countries and were considered “high-risk”. * Results from univariate analysis are available in Table S3.
