  1. #Comprehensive index: the predicted probability of endoscopic disease activity based on the combination of CDAI, CRP and PLpR, and it was calculated using binary logistic regression model (ln(p/1-p) = 0.013*CDAI + 0.072*CRP + 0.067*PLpR-1.650)).
  2. PPV: positive predictive value; NPV: negative predictive value
