Interpretation of the equivalence using 6 selected atlases in multi-atlas brachial plexus autosegmentation compared to using more (7–8) and less (5-4-3-2-1) selected atlases. The shaded area covers the equivalence range of 10 %. ♦ = observed point estimate of outcome difference in each number of atlases, corresponding error bar = two-sided 90 % confidence interval (caps at each end = lower and upper bar bounds of confidence interval). DSC, Dice similarity coefficient; CI, confidence interval
