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

Table 2 The association between FGF21 levels and impulsivity

Variables	BIS total scores		BIS nonPlanning		BIS motor		BIS attention
Variables	r	p	r	p	r	p	r	p
Blood FGF21 Levels (pg/ml)	0.064	0.479	0.036	0. 916	0.083	0.358	0.023	0.798
CSF FGF21 Levels (pg/ml)	−0.577	< 0.001	−0.399	< 0.001	−0.634	< 0.001	−0.375	< 0.001

Partial correlations were used to analyze the relationship between FGF21 levels and impulsivity with the year and education year as covariates. FGF, fibroblast growth factor; BIS, Barratt Impulsiveness Scale
