OHDSI recently posted a release on the IUD study that was run using Columbia Medical Center data; this important study found that patients who used copper intrauterine devices (Cu IUD) were found to have a lower risk of high-grade cervical neoplasms (cervical cancer) compared to users of the levonorgestrel-releasing intrauterine system (LNG-IUS). You can find the full release here: https://www.ohdsi.org/ohdsi-news-updates/iud-study/.
The authors are now looking for community involvement to make this a network study. More information on the study can be found in the release, and it is also available in this forum post.
