Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
