  1. HUI2 = Health Utilities Index Mark 2; HUI3 = Health Utilities Index Mark 3; SF-36 = Short-Form 36; MBSRQ-AS = Multidimensional Body Self Relations Questionnaire Appearance Assessment; BSS Score = Breast Symptom Summary Score; SD= Standard Deviation; ES1 = Effect Size (based on Cohen, 1988); SRM = Standardized Response Mean; SRM = Δ/SD(Δ)
  2. ES1 = Δ / SD at baseline; Difference (Δ) = mean score at 6 month assessment minus mean score at baseline.
  3. * n's reflect the number of patients who have completed the measure at both time-points (baseline and six months) and hence the difference in numbers from Table 1.
