Graph representing the correlation between QLQ-BR23 scores and the first two principal components of Principal Component Analysis at each prospective measurement time (N = 154): at baseline (Panel A), just after surgery (Panel B), at three months (Panel C) and at six months (Panel D). The QLQ-BR23 measures four functional scales (body image (BI), sexual functioning (SEXF), sexual enjoyment (SE), future perspective (FP)) and four symptom scales (systemic therapy side effects (STSE), breast symptoms (BS), arm symptoms (AS), upset by hair loss (HL)). SE and HL are excluded from these analyses.
