Model	Sex	Weighted mean [95 % CI]^a (kg)
Random effect^b	Man	33.11 [32.27:33.96]
Random effect^b	Woman	20.92 [20.45:21.39]
Mixed effect^b,c (meta-regression)	Man	=78.74−0.62 [−0.51:−074]* Age [F(3,32) = 51.33, p < 0.0001]
Mixed effect^b,c (meta-regression)	Woman	=46.90−0.35 [−0.21:−0.43]* Age [F(1,48) = 24.01, p < 0.0001]

^a95 % CIs were estimated using the Knapp and Hartung adjustment

^bDerSimonian–Laird estimator was used for estimation of models

^cSix data for men and 7 for women were excluded from the Mixed effect model because they lacked data on age
