Table III.

Correlations between GDNF, BDNF, SNAPIN, and fatigue (N = 47).

Variables		Fatigue (r_s)
Baseline	Glial cell derived neurotrophic factor (GDNF)	−0.097
	Brain derived neurotrophic factor (BDNF)	−0.197
	SNARE-associated protein (SNAPIN)	0.434^**
Midpoint	Glial cell derived neurotrophic factor (GDNF)	−0.263
	Brain derived neurotrophic factor (BDNF)	−0.158
	SNARE-associated protein (SNAPIN)	0.120

Significant correlations (r_s) in concentrations of neurotrophic factors and fatigue scores at each time point are indicated by P value (**P < 0.01).
