Comparisons of clinical signs of bedridden Guillain–Barré syndrome (GBS) patients without mechanical ventilation in different treatment groups. The incidence of the cranial nerve involvement of the nonmechanically ventilated but bedridden patients in the combination therapy group was higher than the intravenous immunoglobulin (IVIg) treatment group (46.2% vs. 29.6%, P < 0.05) (A). Similarly, the Medical Research Council (MRC) sum score at nadir (28.2 vs. 26.7, P > 0.05) and at discharge (44.7 vs. 41.6, P > 0.05) were comparable between the 2 groups (B), as well as the Hughes Functional Grading Scale (HFGS) score at nadir (4.0 vs. 4.0, P > 0.05) and at discharge (2.8 vs. 3.0, P > 0.05) (C). The efficiency reflected by the ratio of patients who were improved after treatment was not different between the 2 groups either assessed by improvement of MRC (89.6% vs. 86.5%, P > 0.05) or HFGS (69.6% vs. 61.5%, P > 0.05) (D).
