  1. a Abbreviations: SD Standard deviation, IQR Interquartile range, LLOA: Lower limb osteoarthritis, n Number, PA Physical activity
  2. b Participants with at least 4 valid days (≥10 h of wear time per day) of accelerometry data were included in the data analyses
  3. c Light PA: 100–2019 counts/minute; Low-light PA: 100–759 counts/minute; High-light PA: 760–2019 counts/minute; Moderate to vigorous PA: ≥2020 counts/minute
  4. d p-value of observed differences between groups with and without LLOA
