^**

significant at the 0.01 level (2-tailed).

Because HIV needle risk and drug use are binary outcome variables, the −2 log likelihood statistics are presented to indicate the degree of model fit.

Using a stepwise selection method, only variables that resulted in significant improvement in model fit were retained in the final model, and only coefficients for variables retained are presented in the table.

Coefficients presented in this table reflect the final step.
