Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
We aimed to provide the first large-scale, population-based estimate of lifetime risk of AA overall and by important sociodemographic subgroups. As AA is associated with an increased burden of mental health conditions and work-related outcomes (unemployment, time off work), a detailed understanding of the burden of disease in different sociodemographic groups is vital to plan resource provision.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The cumulative lifetime risk of AA was estimated at age 80 years (approximate life expectancy in the UK) using survival models, with age as the timescale and accounting for the competing risk of death.
The assessment of any associations with baseline characteristics and the outcomes of interest will be assessed using Cox proportional hazards models (time to event outcomes) and Poisson regression (repeated event outcomes) models.
