Adjacent legs do not define a cohort
A record must match every selected category to enter the exact cohort.
Read the diagram as text
- Adjacent ribbons are two-category intersections
- A chain minimum is an upper bound on a full intersection
- Select categories across axes
- Query joint-category counts
- Compare 5,269 minimum adjacent contracts with 4,130 exact cohort contracts
A missing classification remains reviewable
The displayed crossing includes naturally occurring and deliberately added records.

- Keep unclassified values as categories
- Bilateral and Unreported define an exact crossing
- The crossing contains 931 records
- 640 are the injected missingness cohort
- Open and reconcile the review cohort
A path intersection is a different count from a leg
Dataset check: 20,000 records; six selected categories

5,269 records - All six selected categories
4,130 records - Shared-looking legs do not define the exact multi-category cohort.
- Keep missing classifications in the review count
- Injected records
640 - Bilateral × Unreported
931 records - Other records
291 - Counts describe records and categories, not notional exposure or contagion.
