  1. SLNB sentinel lymph node biopsy, ALND axillary lymph node dissection, non-BCRL non-breast cancer-related lymphedema, BCRL Breast cancer-related lymphedema
  2. Values are mean ± standard deviation or N (percentage)
  3. aDifferences between BCRL and Non-BCRL were tested by the Mann-Whitney U test and the Pearson’s chi-squared test
  4. bDifferences between BCRL and Non-BCRL were tested by the Student’s t-test and the Pearson’s chi-squared test
  5. cOccasionally, one or more treatments were given to one person
  6. dCircumference difference were calculated by the equation affected length minus the unaffected length
  7. eInactive: Limited physical activity (eg. inpatient)
  8. fSedentary: Most of the time is spent sitting in a static activity
  9. gActive: Most of the time spent sitting, but lifestyle also includes standing work, commuting, buying things, housework, light exercise
  10. hVery active: Strenuous work or highly active leisure
