a Unadjusted odds ratios. Sets of bivariate logistic regressions were performed to determine associations between each independent and control variable and CAM use.

b More conservative 99% confidence intervals were used because of the enhanced statistical power generated by the large sample size.

c Adjusted odds ratios. Each variable is adjusted for all other variables in Tables 1, 2, and 3.

d "Functional limitation" is defined as any difficulty: walking a quarter of a mile, standing for two hours, stooping/bending/kneeling, climbing 10 steps without resting, sitting for two hours, reaching up over the head, using your fingers to grasp small objects, lifting or carrying a 10-pound item, or pushing/pulling a large object.

e "Number of health conditions" is a count variable of approximately 50 chronic and non-chronic conditions found in the Sample Adult core. These include hypertension, coronary heart disease, angina, heart attack, other heart condition, stroke, emphysema, high cholesterol, poor circulation, irregular heartbeats, congestive heart failure, asthma, ulcer, irritable/inflammatory bowel, thyroid problem, urinary problem, food allergy, allergy to medication, multiple sclerosis, Parkinson's disease, neuropathy, seizures, cancer, diabetes, hay fever, sinusitis, chronic bronchitis, weak or failing kidneys, liver condition, arthritis, diabetic retinopathy, cataracts, glaucoma, macular degeneration, insomnia, fatigue, recurring pain, depression, severe sprain or strains, dental pain, skin problems, joint pain, neck pain, low back pain, facial pain, severe headache or migraine, head or chest cold, and stomach or intestinal illness.

f "Delayed conventional care for reasons other than cost" is coded "yes" if the sample adult: couldn't get through on the telephone, couldn't get an appointment soon enough, had to wait too long to see the doctor, couldn't get to a clinic or doctor's office when open, or didn't have transportation.
