aOnly factors with a significant association at .2 alpha risk in the bivariate regressions were candidates for entering into the multivariate model (n=89).
bP value is the level of significance of the test of the OR against 1.
cFor age, N, n, and % describe the total sample and as age is a quantitative variable, the OR corresponds to 1 year age increase.
