Error bar chart showing the relation of mean difference 90% confidence Intervals to various equivalence intervals.
DXA stands for dual emission x-ray absorptiometry; BIA stands from bioelectrical impedance analysis; IR stands for near infrared reactance; ADP stands for air displacement plethysmography; x-axis is mean difference from percent body fat measured using hydrostatic weighing; upper and lower bounds of the Equivalence Intervals are denoted by dashed vertical lines; red dashed lines is the 5% Equivalence Interval; blue dashed lines is the 10% Equivalence Interval; black dashed lines is the 15% Equivalence Interval; Equivalence denoted by a respective 90% Confidence Interval falling within Equivalence Interval.
