aClinical case definitions according to the Brighton Collaboration Criteria: Guillain–Barré Syndrome or Miller Fisher syndrome (MFS): Level 1 of diagnostic certainty: clinical, electrophysiological and cerebrospinal fluid (CSF) findings consistent with GBS (or MFS), in the absence of an identified alternative diagnosis. Level 2 of diagnostic certainty: clinical and either electrophysiological or CSF findings consistent with GBS (or MFS), in the absence of an identified alternative diagnosis. Level 3 of diagnostic certainty: only clinical findings consistent with GBS (or MFS), in the absence of an identified alternative diagnosis
