  1. $Exception: age ≥ 82 years showed a negative association with progression, compared to age ≤ 62 years
  2. $$Pain at baseline measured with NRS past week showed a statistically significant positive association with THR; pain at baseline measured with WOMAC pain showed no statistically significant association with THR
