Quantifying hepatitis C transmission risk using a new weighted scoring system for the Blood-Borne Virus Transmission Risk Assessment Questionnaire (BBV-TRAQ): Applications for community-based HCV surveillance, education and prevention

Table 4 Comparisons between self-report HCV status groups for unweighted and weighted BBV-TRAQ total and injecting subscales scores

Weights	BBV-TRAQ Score	F	p-value	mean difference (HCV positive & negative)	95% CI of the difference
None	Injecting subscale	2.46	.141	3	-1 – 7
	Total	0.76	.997	2	-4 – 8
Log one	Injecting subscale	3.04	.080	15	-1 – 31
	Total	1.98	.250	14	-5 – 32
Log two	Injecting subscale	3.63	.038	40	2 – 79
	Total	2.97	.078	39	-3 – 80
Log five	Injecting subscale	4.12	.017	1,293	176 – 2,411
	Total	3.86	.023	1,273	132 – 2,414

* Comparisons were made between all HCV groups (i.e., inclusive of 'never tested/not sure' group). To simplify tables only results relevant to the focus of this paper have been presented (i.e., 'HCV positive' and 'HCV negative'). No differences were detected between the 'never tested/not sure' and other groups.
