Bland–Altman plots comparing differences between DXA, DLW and BIS+MFBIA to assess changes in body composition between baseline and after 12-week intervention (AB) in overweight and obese initially lactating women postpartum. Horizontal dotted line=mean difference (kg). Limits of agreement correspond to±2 s.d. Regression line=difference between reference method minus bioimpedance method as dependent variable, and mean of reference method minus bioimpedance method as independent variable, with rPearson and P-values inserted. (a and b) Differences in FM changes by BIS and MFBIA compared with DXA. (c and d) Differences in TBW changes by BIS and MFBIA compared with DLW. (e and f) Differences in SMM changes by BIS and MFBIA compared with DXA. BIS (Xitron 4200); MFBIA (Tanita MC-180 MA II).
