NB, neuroborreliosis; ACA, acrodermatitis chronicum atrophicans; chronic > 6 months’ duration; subacute < 6 months’ duration; CSF, cerebrospinal fluid; MNC, mononuclear cell; n.d., not done.
Borrelia-specific CSF antibody index was defined according to Hansen and Lebech, 1991.
Mononuclear pleocytosis in CSF was defined as positive if ≥ 5·0 × 106 mononuclear cells/l.
CSF albumin quotient was defined as positive if > 8·1 × 103.
IgG synthesis index in CSF was defined as positive if >1·25.
