Mediation effects of multiple adult risk factors on the adult BMI-cIMT association

β, c and c’ are standardized regression coefficients.

c=total effect; c’=direct effect; β₁=indirect effect 1; β₂=indirect effect 2; β_Ind=indirect effect; BMI=body mass index; cIMT=carotid intima-media thickness; SBP=systolic blood pressure; LDLC=low-density lipoprotein cholesterol; AIP=atherogenic index of plasma

Total β_Ind= 0.065, P < 0.001 (the sum of the four indirect effects)

* P < 0.05 and ^† P < 0.01 for being different from 0
