Table 2

Results from the analyses of patient HCV testing rates and positivity rates (number positive/number tested) and practice characteristics.

	Testing rates			Positivity rates^a

Factor	Adjusted rate ratio^b	95% CI	P-value	Adjusted rate ratio^b	95% CI	P-value
Deprivation (Townsend fifths):
1 (most affluent)	1.00			1.00
2	1.04	(0.60 to 1.80)	0.90	0.41	(0.19 to 0.88)	0.02
3	0.55	(0.31 to 0.97)	0.04	0.60	(0.26 to 1.39)	0.23
4	1.12	(0.63 to 1.98)	0.71	0.41	(0.19 to 0.92)	0.03
5 (least affluent)	1.15	(0.64 to 2.09)	0.64	0.39	(0.17 to 0.91)	0.03
Test for trend			0.48			0.09

Urban versus rural practice	1.01	(0.54 to 1.89)	0.97	0.91	(0.37 to 2.21)	0.84

Single-handed practice versus partnership	2.77	(1.85 to 4.16)	0.001	1.88	(1.05 to 3.36)	0.03

GP training practice (yes versus no)	0.91	(0.60 to 1.37)	0.64	0.91	(0.50 to 1.64)	0.75

Practice with 50% female GPs or more	1.59	(1.13 to 2.25)	0.009	0.51	(0.28 to 0.91)	0.02

Practices with mean age of GPs in practice ≥45 years	0.92	(0.67 to 1.26)	0.61	0.76	(0.46 to 1.24)	0.27

↵a Excludes 12 practices where no patients were tested.
↵b Adjusted for other factors in table and % males in practice aged 15–24 years and % males aged 25-44 years. HCV = hepatitis C virus.
