Examples of a GBS and a CIDP patient before and 6 months after therapy. A1 and A2 reveal the course in a GBS patient with a significant decrease of nerve root enlargement (cervical root 6, C6; 4.8 to 4.1 mm, reference < 4.2 mm, according to 14) compared with a CIDP patient. Here, the cervical root 6 (B1 and B2 5.6 and 5.5 mm) and the median nerve (C1 and C2, 48 mm² and 49 mm², reference < 12 mm², 14) are similarly enlarged in both examinations
