Table 4 The multivariable linear regression analysis between CSF FGF21 and other variables

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

  BIS total scores CSF serotonin (pg/ml) CSF dopamine (pg/ml)
β coefficient (95% CI) β coefficient (95% CI) β coefficient (95% CI)
CSF FGF21 (pg/ml)
