  1. Results are given as median (quartiles).
  2. Pn-nf: Children with pneumonia after complete remission.
  3. PFAPA-nf: Children with PFAPA between febrile episodes.
  4. PFAPA-f: Children with PFAPA during febrile episodes.
  5. Pn-f: Children with pneumonia shortly after admission.
  6. ns: not significant.
  7. * Lymphocytes, monocytes and eosinophils were measured in 12 children with Pn-f.
