Fibroblast growth factor 21 associating with serotonin and dopamine in the cerebrospinal fluid predicts impulsivity in healthy subjects

Table 3 The association between CSF serotonin, CSF Dopamine levels, and impulsivity

Variables	BIS total scores		BIS nonPlanning		BIS motor		BIS attention
Variables	r	p	r	p	r	p	r	p
CSF serotonin (pg/ml)	−0.261	0.003	−0.131	0.151	−0.324	< 0.001	−0.152	0.092
CSF Dopamine (pg/ml)	−0.264	0.003	−0.166	0.066	−0.284	< 0.001	−0.179	0.046

Partial correlations were used to analyze the relationship between impulsivity and CSF serotonin or dopamine with the year and education year as covariates. FGF, fibroblast growth factor; BIS, Barratt Impulsiveness Scale.
