How Myelofibrosis is matched — 8 exact registry spellings

A study is on this page when its ClinicalTrials.gov record names one of these conditions exactly (letter case aside). Nothing is matched by substring or stem, so a longer condition that merely contains one of these words is a different page. The list was curated by hand and last measured 2026-08-19; a spelling filed by only one study was not curated, so the counts here are a floor rather than the registry's own total for the disease.

  • Myelofibrosis
  • Primary Myelofibrosis
  • Myelofibrosis (MF)
  • Post-essential Thrombocythemia Myelofibrosis
  • Post-polycythemia Vera Myelofibrosis
  • Post Essential Thrombocythemia Myelofibrosis
  • Post Polycythemia Vera Myelofibrosis
