Influence of type of radiation therapy on trajectories of quality of life. Graphical representation of the relationship between type of radiotherapy (WBRT = whole breast radiation therapy, PBRT = partial breast radiation therapy) and quality of life (FACT-G scores, score range 0–108) as estimated by the hierarchical linear model from the time of the initial assessment (Baseline) to 6 weeks post radiotherapy. At the initial assessment, groups did not differ with respect to quality of life. However, quality of life declined for women who received WBRT, whereas quality of life increased for women who received PBRT over the 6 weeks post radiation therapy. *bslope x group = 1.11, p = 0.05.
