Fig. 2From: Validity of ultrasonography-derived predictions for estimating skeletal muscle volume: a systematic literature reviewBland–Altman agreement, differences plotted in percentages for the studies that reported MVUS. Total body estimates are excluded in the plots. Values in plot A for the studies that reported data in cm3: Bias − 1%, SD 4%, limits of agreement upper 7% and lower − 8%. Values in plot B for the studies that reported data in kg: Bias − 6%, SD 13%, limits of agreement upper 20% and lower − 32%Back to article page
