How Long COVID studies are organized in the registry

Terminology for this condition is unusually inconsistent across the registry: the same kind of study may be filed under “long COVID,” “post-acute sequelae of SARS-CoV-2,” the abbreviation PASC, or “post-COVID conditions.” Trying more than one of these terms is the single most effective way to avoid missing records.

  • 69% of the 39 locally indexed Long COVID records are currently marked recruiting.
  • The most common phase group in the local index is Not applicable (15 records).
  • The most frequent sponsor is Icahn School of Medicine at Mount Sinai (4 records).
  • The most listed study location is Boston, Massachusetts (6 records).
