Predictive value of a nomogram model for treatment response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer

Figure 1 Nomogram model for predicting neoadjuvant chemoradiotherapy response in patients with locally advanced rectal cancer. CEA: Carcinoembryonic antigen; CRP: C-reactive protein; IL-6: Interleukin-6.

Figure 2 Receiver operating characteristic curve assessing the nomogram’s predictive accuracy for neoadjuvant chemoradiotherapy. AUC: Area under the curve.

Figure 3  Calibration curve demonstrating agreement between predicted and observed responses in the nomogram model.

Figure 4  Decision curve analysis illustrating the net benefit of the nomogram for predicting neoadjuvant chemoradiotherapy response.
