All measurements were based on the drawings. The average center position was the average x coordinate and the average y coordinate of all drawings in the lymph node station. The agreement was defined by the proportion with center point within 1 cm from the average center point, and area below 2 cm²; High if >80 %, Intermediate: 70–80 %, Low: <70 %
