Primary Outcomes (End Points)

Before
The confirmatory outcomes are number of quarters employed during the 15-month follow-up period and total earnings during the follow-up period. Exploratory outcome variables include quarterly employment rates, quarterly earnings, and other outcomes related to employment, health, Social Security benefit applications, substance use disorder recovery, and housing stability.

After
The confirmatory outcomes are number of quarters employed during the 15-month follow-up period, total earnings during the follow-up period, and ever employed in the last quarter of the follow-up period (full disclosure: this third primary outcome variable was added after the beginning of the analysis. The reason is that the team had decided to add this as a primary measure when developing the pre-analysis plan. Unfortunately, the team did not catch that this pre-analysis plan was in conflict with the registry and did not edit the registry upon finalizing the pre-analysis plan). Exploratory outcome variables include quarterly employment rates, quarterly earnings, and other outcomes related to employment, health, Social Security benefit applications, substance use disorder recovery, and housing stability.
