The Mediating Effect of Serum MOTS-C in the Association of BMI and RHI in Children

Factors Coefficient Effect Value Z-value P-value
ab −0.0047 2.481 0.019
Inline graphic c′ −0.046 3.597 < 0.001
Mediating effect ratio 0.0912

Notes: Adjusted for age. BMI, MOTS-C and RHI were set as independent variable X, intermediate variable M and dependent variable Y, respectively. The mediating effect value was represented by ab which be obtained by multiplying a and b from the equations of Inline graphic and Inline graphic. The c′ was the effect of X on Y after adjusting M. The mediating effect ratio was the absolute value of ab/ (ab+ c′) a.

Abbreviations: RHI, Reactive hyperemia index; BMI, Body mass index.
