Reliability and predictive validity of a hepatitis-related symptom inventory in HIV-infected individuals referred for Hepatitis C treatment

Table 2 Unadjusted Generalized estimating equations models of treatment period (pre therapy vs. on HCV therapy)

Model	Score	B₀ (Constant)	B₁ (coefficient)	95% confidence interval	P
1	Sum symptoms	53.27	6.92	2.23 to 11.61	0.004
2	CES-D	7.31	1.86	-0.01 to 9.36	0.05
3	Neuropsychiatric symptoms	18.26	2.55	0.73 to 4.38	0.006
4	Somatic symptoms	14.30	2.57	1.01 to 4.14	0.001
5	Sleep symptoms	2.93	0.45	-0.08 to 0.98	0.09

Effects on symptoms and CES-D scales cores (n = 31).
CES-D = Center for Epidemiologic Studies Depression Scale
Each model had the form:
score = B₀ + B₁ (treatment period); where treatment = 1 if on therapy and 0 if before therapy.
