Distance between the center of mass of marker contours propagated by the Ethos software, i.e. Marker_auto and manually delineated, i.e. Marker_man (N = 10 patients; n = number of sessions). The boxplots represent the 1st and 3rd quartile, the line inside the median and the whiskers represent the range. “GTV corrected” represents the sessions where the GTV was online adjusted. “GTV accepted” represents the sessions where the propagated GTV was accepted. No significant difference was found between these two groups (p < 0.001)
