Differences in daily costs of crime associated with opioid agonist treatment (OAT) and detoxification, (reference group: post-treatment) estimated from Average Marginal Effects (AME). Respective AME are generated from each distinct two-part model: baseline, treatment-specific post-treatment models using post-OAT and post-detoxification episodes, and for each of the mutually exclusive longitudinal treatment access patterns, defined as OAT only, detoxification only, detoxification once and OAT once or more, and multiple detoxification and OAT episodes.
