Fig. 3From: Lyme borreliosis in Finland: a register-based linkage studyThe distribution of microbiologically confirmed Lyme borreliosis cases among Avohilmo and Hilmo. “Any event (ICD-10) in Hilmo” refers to microbiologically confirmed LB cases that were notified to Hilmo with any other ICD-10 code except “A69.2”. Most of the microbiologically confirmed LB cases in NIDR that could not be linked to any records in Avohilmo or Hilmo were probably diagnosed in the occupational or private health care. Avohilmo = The Register for Primary Health Care Visits, Hilmo = National Hospital Discharge Register, ICD-10 = International Classification of Diseases, revision 10, LB = Lyme borreliosis, NIDR = National Infectious Diseases RegisterBack to article page
