Fig. 3From: High inter-observer reliability in standardized ultrasound measurements of subcutaneous adipose tissue in children aged three to six yearsObserver differences from the mean. Individual observer differences (Δ) from the mean of the three measurements (DMEAN) are shown for each participant (see Table 2). a Individual observer differences from DMEAN including embedded structures (DI,MEAN) calculated as ΔI = DI–DI,MEAN are shown. Standard deviation (SD) of observer differences was 1.1 mm, 95% of the measurements were between ±2.1 mm (limits of agreement). b Individual observer differences ΔE = DI– DE,MEAN are shown. SD of observer differences was 1.0 mm, 95% of measurements were between ±2.0 mm (limits of agreement)Back to article page
