Comparison of the change from baseline in CDAI and HBI scores from PRECiSE 1 and PRECiSE 2. (A) Dashed lines indicate CDAI response with a change in CDAI of ≥100 points and HBI response with a change in HBI score of ≥3 points. The solid line indicates the regression curve. Spearman correlation coefficient, r = (B) Dashed lines indicate CDAI remission at ≤150 points and HBI remission at ≤4 points. The solid line indicates the regression curve.
