Table 4 A multivariate logistic regression analysis. The cut-off values for ROM and CRP at 12 weeks were used as variables. ORs and 95% CIs were calculated between patients with scores higher than and lower than the cut-off values. The cut-off values for receiver operating characteristic (ROC) curves were determined by the maximum of a Youden index
