  1. *SF-12 PCS: Short Form 12 physical component score †pSF-12: proxy version of SF-12
  2. ‡I-QOL: Incontinence quality of life scale §pUI: proxy urinary incontinence, ¶FES: falls efficacy scale, #SD: standard deviation.
  3. Note: Number of patients that had SF-12 and pSF-12 scales are different because some patients had missing values.
