  • ESR, erythrocyte sedimentation rate; PGA, physician’s global assessment.

  • Non-adjusted odds ratios (OR) were calculated by univariate logistic regression analysis.

  • Adjusted values were calculated using a multivariate regression analysis, adjusting for JIA type and medication use with the propensity score.

  • PGA scores of up to 0.3 (10% of the maximum scale) were considered normal.
