Box and whisker plots of CTV and OAR doses and dose differences for a and b all patients, c all breast patients, d all CW patients, and e and f all patients with at least three V-CTs. The horizontal lines and crosses in the boxes are the medians and averages. The circles are outlier points. The numbers blow the boxes are the mean ± 1SD. The pink shaded areas are the regions where CTV coverages or OAR doses were worse on V-CT/cumulative doses than those on planned doses. CTV, clinical target volume; CW, chest wall; SCV, supraclavicular node; IMN, internal mammary nodes; OAR, organ at risk; V-CT, verification computed tomography; P-CT, planning computed tomography; SD, standard deviation; cum, cumulative
