B, the regression coefficient estimates. B can be interpreted as the amount of increase (or decrease, if the sign of the coefficient is negative) in the predicted log odds of the number of zero use days “abstinent days”/and increase (or decrease if negative) in days of use between substance users when using MICBT intervention holding all other predictors constant. OR (exp B), odds ratios. The OR can be interpreted as the increase (above 1.0) or decrease (below 1.0) in the odds of not using days between MICBT participants (with other predictors in the model held constant)
IRR, incidence rate ratio. The IRR can be interpreted as a percentage increase (above 1.0) or decrease (below 1.0) in drug use days with participants of the MICBT group
^*Significant P value (< 0.05)
^**Highly significant P value (< .001)
