A was a nomogram. B was the calibration curve for the nomogram. The diagonal dashed reference line represents a perfect estimated MSI status for an ideal model. Solid lines represent the estimated MSI status of the nomogram. C was the decision curve analysis for the nomogram. The black line indicates the assumption that all patients are diagnosed not to be MSI-H, and the grey line indicates the assumption that all patients are diagnosed to be MSI-H. The red line represents the nomogram
