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

bMore 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.
