The overall prevalence of inpatient conditions in the raw data was compared to that in the common data model (CDM) with the standardized visit definition applied.
Our main motivation for this study was to assess the impact of applying a standard visit definition to two claims databases on the prevalence of health service utilization and disease prevalence observed during inpatient encounters.

Consequently, re-visiting the epigenetic definition of CGIs and providing an experimentally defined CGI catalog that overcomes the limitations of computational predictions will offer a tremendous resource for advancing our knowledge.
The associations were similar for both of the hypertension definitions used, although our findings were more robust for the self-reported hypertension outcome as compared with the visit-based definition, perhaps because of increased statistical power (5,177 self-reported vs. 1,789 visit-based hypertension cases).
We used two definitions of incident diabetes: a visit-based definition (definition A) and an interview-based definition (definition B).
