The adjusted probabilities of arrests in a given month were 3.7 percent for the reference group, 2.8 percent for people who currently have a voluntary agreement, and 1.9 percent for people who currently have AOTs. Study 2 All group analyses by Link and colleagues (2011) showed that the risk of arresting people before assisted outpatient treatment (AOT) was significantly higher than during the AOT period. Although the risk of arrest increased slightly after stopping AOT, this difference was not significant. For a person who had already received an AOT, the risk of arrest before AOT was 2.66 times higher than during the AOT. .
