N = 974. Tabled values are odds ratios and 95% confidence intervals for each predictor (column) predicting initiation of substance at the indicated age by row. Significant odds ratios greater than 1.0 indicate positive relations. ‘--‘ indicates a prediction path excluded from the model. Significant effects, p < .05, in bold type.
