DCA of the clinical usefulness for nomogram in 3 months and 6 months. Decision curve for the model in predicting 3 months (A), 6 months (B) remission rate of development cohort. Decision curve for the model in predicting 3 months (C), 6 months (D) remission rate of validation cohort. Standard net benefit (y-axis) and risk threshold (x-axis) formed the coordinate system. The blue line represents our model, the red line represents the assumption that all the people have been treated, and the green line represents the assumption that all the people have not been treated. DCA, decision curve analysis.
