A Predictive Model and Survival Analysis for Tube Feeding in ALS Patients: A Prospective Cohort Study in a Chinese ALS Clinic

Figure 3

Receiver operating characteristic (ROC) curve and calibration curves of the nomogram. (a) The area under the curve (AUC) of using the nomogram to predict tube feeding-free probability, , which is considered ideal. (b–d) Calibration curves of 1-year, 2-year, and 3-year tube feeding-free prediction probability. The light blue line indicates the ideal reference line where predicted probabilities would match the observed prediction rates. The red dots are calculated by bootstrapping (resample: 1,000) and represent the performance of the nomogram.
