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

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

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