Corpus Insights
Patterns across the whole predicate graph — not just one device's own lineage.
Most frequently reused predicates
The devices other 510(k) submissions cite as "substantially equivalent" most often — the load-bearing precedents this corpus's regulatory history actually runs through.

Devices with the deepest reach
Not just direct citations — everything that eventually traces back through a device at any depth. A different measure than reuse count on the other tab: a device can be a foundational ancestor even if few submissions cite it directly, so long as the ones that do go on to be cited themselves.

Largest predicate families
Devices grouped by connectivity, ignoring citation direction — if A cites B and C cites B, A and C are in the same family even though they never cite each other directly. Most families are small (2-5 devices), but a handful span hundreds — genuinely distinct clusters, not an artifact of the graph. Each row is the most-connected device in its family, standing in for the whole cluster.

Longest predicate chains
The devices whose own regulatory ancestry runs deepest — not how many other devices cite them (that's the other tabs), but how many generations back their own chain of predicates goes before it stops. The homepage's "See a real predicate lineage" link uses one of these.
