Table 4 Predictors of Knowledge of, Experience with, Expectations about, and Willingness to Try Five Complementary and Alternative Medical (CAM) Therapies

From: Complementary and alternative medical therapies for chronic low back pain: What treatments are patients willing to try?

  Odds ratios* (95% CI) for the independent predictor variables used in the final models for each CAM therapy
Dependent Variable Acupuncture Chiropractic Massage Meditation T'ai chi
High Knowledge of specific therapy (4–5) Tried acupuncture: 43.6 (16.7–113.6) Tried chiropractic: 12.8 (6.2–26.7) Tried massage: 7.6 (4.0 – 14.7) Tried meditation: 11.6 (4.6–29.3) LOGISTIC NOT VALID**
     Bostonian: 4.8 (1.9–12.3)  
Previously tried specific therapy No associations Bostonian: 0.5 (0.3 – 0.8) 65+ yrs: 0.4 (0.2 – 0.7) Female: 2.5 (1.3 – 4.8) No associations
Previously tried specific therapy for back pain No associations None 65+ yrs: 0.3 (0.2 – 0.6) No associations LOGISTIC NOT VALID**
High expectations of specific therapy (7 – 10) 65+ yrs: 0.4(0.2 – 0.8) Knowledge: 2.9 (1.6 – 5.2) 65+ yrs: 0.3 (0.2 – 0.5) No associations No associations
  Tried acupuncture: 4.3 (2.1 – 9.0)     
Very likely to try specific therapy for free High expectations: 15.4 (3.6 – 66.1) High expectations: 27.4 (9.5 – 79.3) High expectations: 16.4 (7.4 – 36.5) High expectations: 3.6 (1.7 – 7.7) High expectations: 14.3 (5.4 – 38.3)
     Tried meditation: 2.4 (1.3 – 4.5)  
Very likely to try specific therapy for $10 /visit co-pay High expectations: 6.8 (3.0 – 15.5) High expectations: 8.1 (4.2 – 15.7) High expectations: 6.4 (3.5 – 11.4) NOT QUERIED NOT QUERIED
  Bostonian: 2.3 (1.4 – 4.0)   Bostonian: 1.8 (1.001 – 3.2)   
  1. *These odds ratios describe the significant associations (p < 0.01) for each of the 28 therapy – specific dependent variables. For example, we found that those who had tried acupuncture were 43.6 times more likely to have high knowledge of acupuncture. No other variables were related to high knowledge of acupuncture. ** These logistic regression models did not converge. Categorization for independent variables: Age (<65; 65+) Knowledge of therapy (1–3; 4–5) Gender (M; F) Expectations of therapy (missing through 6; 7+) Geography (Seattle; Boston) Prior Use of therapy (no; yes)
