  1. JKOM Japanese Knee Osteoarthritis Measure, OR Odds ratio; 95% CI: 95% confidence interval
  2. a Proportional OR (95% CI) for a greater quartile (JKOM pain and stiffness; 1–4; 1 [< 25th percentile] indicates mild pain and 4 [≥75 percentile] indicates severe pain) or greater task-specific knee pain (1: no pain, 2: mild pain, 3: moderate/severe pain) was calculated (continuous) to indicate predictive ability of the presence of depression while simultaneously including (one-step model) age (continuous), sex, body mass index (continuous), index knee radiographic tibiofemoral joint Kellgren/Lawrence grade (continuous), and objectively measured physical activity (continuous) in the ordinal regression model
  3. See Additional file 1: Table S1 for details of quartiles in JKOM “pain and stiffness”
  4. Bold represents statistically significant result
