Brief Summary
International GBS Outcome Study (IGOS) is a study conducted by the members of the Inflammatory Neuropathy Consortium (INC) and Peripheral Nerve Society (PNS) on disease course and outcome in Guillain-Barré syndrome (GBS). The IGOS aims to identify clinical and biological determinants and predictors of disease course and outcome in individual patients with Guillain-Barré syndrome, as early as possible after onset of disease.
