  2. *AFM showed strong interdependence with the sub-scapular fat mass (SSFM) measurement, therefore, for the linear regression analysis only AFM was selected. Linear model including SSFM revealed that it was also an independent predictor of the fetal birth-weight [63.0, 95% CI (1.4–124.7), p < .05; adjusted R2 = .66]
