Intraobserver landmark placement error. Intraobserver error of each landmark (LM) for each observer at E10.5 (A), E11.5 (B), and E12.5 (C), calculated as the euclidian distance between the landmark coordinates recorded in the two landmark placement trials. The calculations are combined for left and right versions of bilateral landmarks. The reference value of 0.1 mm discussed in the paper is shown as a dotted horizontal line. Observers 1, 2, and 3 are experienced with landmarking, while observer 4 is a first time landmarker.
