  1. Margin sizes between contrast enriching tumor volumes and beam collimation settings in H- and L-axis [mm] as means over time (d7, d10, d14, d17) or as single values of d7 and overall survival times [d] were subjected to univariate Cox proportional hazard model analyses and post-hoc Bonferroni-Holm correction
