Comparison among clinical data of the GBS, CIDP, and Control groups, x ± s.

Subjects	All patients	Age (years)	Sex		HFGS
			Male	Female
GBS group	97	49.04 ± 16.19	51	46	3.71 ± 0.52
CIDP group	78	51.67 ± 13.31	57	21	3.85 ± 0.40
Control group	81	34.98 ± 12.22	30	51	0.10 ± 0.30
F/χ2		32.79	20.88		2,088.69
P		0.00**	0.00**		0.00**

Differences in sex were statistically significant between the GBS and CIDP groups (χ² = 7.69, P < 0.01), while HFGS showed no significant difference (P > 0.05). Age and HFGS in the GBS and CIDP groups were higher than those in the control group (**P < 0.01).
