Assert Non-Zero Medication Exposure Coverage Across Sites — assert_exposure_coverage • omopduckdb

Verifies that medication classes have non-zero (or expected) exposure coverage across sites, preventing silent-zero data drops.

Usage

assert_exposure_coverage(
  flags,
  classes = NULL,
  min_n = 1000,
  site_col = "site",
  min_prevalence = 0
)

Arguments

flags: Data frame with exposure flags (from extract_medication_classes()).
classes: Classes to check (default: all base class columns).
min_n: Minimum site cohort size required to trigger assertion (default 1000).
site_col: Site column name (default 'site').
min_prevalence: Minimum expected prevalence threshold (default 0.0).

Value

Invisibly returns NULL; throws an error if assertion fails.
