Flow chart describes the understaged and overstaged group based on overestimated or underestimated clinical (c)T or cN. Only patients who changed from stage group to another were taken into account. The “other” understaged group comprises patients who switched stage based on a larger T stage but had a smaller pathologic (p)N stage; for example: cT2a N1 to pT3 N0 is a switch from stage IIa to IIB). In the “other” overstaged group, this is the other way around.
