Anterior and lateral views of RNRs and RNR epicentres. Anterior view of contoured RNRs (a-d)*: a all patients, b nodal RT, c tangents d no RT; anterior view of RNR epicentres (e-h)*^#: e all patients, f nodal RT, g tangents, h no RT; lateral view of RNR epicentres (i-l)*^#: i all patients, j nodal RT, k tangents, l no RT. *Colour scheme of overlap of contoured nodes: Blue = one node, yellow = overlap of two nodes, Orange = overlap of three nodes, Red = overlap of four nodes. ^#Colour scheme of RTOG-CTVs: Cyan = Supraclavicular; Yellow = Axilla level I; Magenta = Axilla level II; Blue = Axilla level III; Green = IMC
