  1. JE joint erosion, JSN joint space narrowing, mTSS modified total Sharp score, DAS28 28-joint count Disease Activity Scoreg
  2. Data are presented as mean (standard deviation, SD) and median (interquartile range, IQR)
  3. The p values were calculated using analysis of covariance with treatment as a covariate
