I am replicating dementia prediction models from literature and creating cohorts in ATLAS that will be used as custom covariates in a Cox regression model. The model that I am currently replicating is by Walters (Link) where one of the model’s predictors is social deprivation, defined as the Townsend local area deprivation quintile with a scale from 1=least deprived to 5=most deprived.
The development data of Walters’ model comes from the THIN database in the UK, which I assume has information about the Townsend local area deprivation quintile. Can anyone working with THIN UK data confirm this?
So I started looking for ways to model this scale, but have only been able to define a binary variable from it as follow:
I wonder if anyone has experience with the THIN database, or maybe was involved in mapping it to the OMOP CDM, and can give me a hint on where to find back the Townsend local area deprivation quintile in one of the CDM’s standard vocabularies.
