Bland Altman Plot: Interfragmentary motion Δz. The differences of interfragmentary motion (Δz) between the dial indicator and PONOTS 5 M are plotted against the average of the two methods. The solid line indicates the systematic bias between the two methods. The upper and lower limits show the 95% limits of agreement.
