OnCo record `2021` (Year). Data CC BY-NC 4.0, attribute "Data from OnCo (onco.cc)"; commercial use needs a licence.

## TL;DR

Everything OnCo dates to 2021: 793 entries, 197 papers, 194 papers listed on people's pages, 134 landmarks and 97 trials reported. Each line links to the record it was read from, so the year is a view of the corpus rather than a second copy of it.

## Summary

793 dated entries in OnCo fall in 2021: 197 papers, 194 papers listed on people's pages, 134 landmarks, 97 trials reported, 77 approvals, 32 regulatory events, 26 financing rounds, 11 companies founded, 10 guideline changes, 7 technologies, 6 laws and regulations and 2 journals founded.

Of those, 24 to the day, 18 to the month and 751 to the year only. Most of the corpus dates a fact to the year, because that is what the source it was read from gives; regulatory events and the readout calendar are the parts that carry a full date.

Everything on this page is generated from the other records. It holds no fact of its own, and it changes when they do.
