Influence of type of radiation therapy on trajectories of fatigue. Graphical representation of the relationship between type of radiotherapy (WBRT = whole breast radiation therapy, PBRT = partial breast radiation therapy) and fatigue (FACT-F scores, score range 0–52) as estimated by the hierarchical linear model. Note higher score indicates less fatigue from the time of the initial assessment (Baseline) to 6 weeks post radiotherapy. Level of fatigue was similar for both groups at the initial assessment. Fatigue increased for women who received WBRT and decreased for women who received PBRT over the 6 weeks post radiation therapy. *b_{slope x group} = 1.11, p = 0.04.
