GBS disability score	2.085	8.042	0.556	116.428	0.126
Cranial nerve involvement	2.424	11.289	1.101	115.743	0.04

Age was dichotomized according to the following criterion: >60 years = 1, ≤ 60 years = 0. The GBS disability score was dichotomized according to the following criterion: GBS score 1 or 2: 0; GBS 3-5:1. CI, confident interval; CMV, cytomegalovirus; GBS, Guillain–Barrè Syndrome; OR, odds ratio.
