Table 4 Summary of Other Secondary Multivariate Regression Models, with alternate key independent variables (N = 498)

From: Chronic disease and recent addiction treatment utilization among alcohol and drug dependent adults

  Model 1 Model 2 Model 3
  Any Addiction Treatment Outpatient Days Residential Nights
Key Independent Variable AOR (95% CI) IRR (95% CI) IRR (95% CI)
Asthma 1.05 (0.74, 1.49) 1.03 (0.52, 2.03) 1.03 (0.50, 2.12)
Self-reported health status    
   Excellent/Very Good/Good Referent Referent Referent
   Fair/Poor 0.67 (0.48, 0.94)* 0.40 (0.20, 0.80)** 0.61 (0.31, 1.21)
Physical Component Score (per 1 point increase) 1.01 (0.99, 1.03) 1.00 (0.97, 1.04) 1.01 (0.97, 1.04)
  1. Model 1 used logistic regression; Models 2 and 3 used Poisson regression. Models duplicate those in Table 3 (controlling for age, gender, race, substance dependence, recruitment from detox, criminal justice involvement, homeless, unemployed, health insurance, smoker, anxiety), solely replacing the chronic disease variable with the secondary variables above.
  2. *p < .05 **p < .01; Wald chi-square tests, df = 1
