Regarding Incidence rate analysis

[Chris_Knoll]

Hi @gyeol99,

@gyeol99

Although this may not be an issue for subjects with only one observation period but for subjects with multiple observation periods, a question remains on whether the “all days before” criteria is really “all days before”.

Only looking within the index’s observation period was the convention in cohort definitions, but since people have been running into the issue you describe, an enhancement will be available in the next release:

By ‘allowing events outside observation period’, it will ignore the observation period bounds, and you can find those prior events that fall outside your observation period, and exclude them from the cohort.
