Fig. 6From: The precision of gingival recession measurements is increased by an automated curvature analysis methodScatter plots displaying correlation of curvature and manual CEJ points distance deviation, i.e., the distance between manual and automated curvature-based CEJ reference point position. The upper row shows the first round of measurement (a–c), and the lower row shows the second round of measurements (d–f). The same colour legend is used as in Figs. 2 and 3 and i.e., Examiner No. 1—red, No. 2—blue, and No. 3—greenBack to article page
