  "disclosure": "Published by AEXTech Holdings. Its founder, Alex Rogers, holds shares in Sera Prognostics, maker of the PreTRM mid-pregnancy risk test that appears on the timeline, and has an interest in a Blue Ox Healthcare Partners vehicle holding Sera warrants; he expects to have a stake in iMSO, a new company that plans to sell preterm-birth prevention programs using that test. Sera did not fund, review or see the site. AEXTech also sells a fuller version of the model behind it. Full text: https://themissingweeks.org/about.html",
