Relationship of baseline adipokines and body composition There was a positive trend in the association between fasting FGF21 and BMI ( r = 0.49; P = 0.09) after adjustment for sex, but not with other baseline measurements ( Table 2 ).
There is a trend of a positive relationship between adiponectin concentration and the EE increase after cold-induced BAT activation but this failed to reach statistical significance, probably due to the small sample size and the relatively larger variation of EE increase of our participants.
