Cumulative incidence of NRM at 6 months based on clinical and MAGIC response criteria in the training and validation sets. (A) Training set. Left: clinical responders: 9.7% (95% CI, 7.6%-12.0%), clinical nonresponders: 36.4% (95% CI, 29.0%-43.8%). Middle: MAGIC composite responders: 5.8% (95% CI, 4.1%-7.9%), MAGIC composite nonresponders: 39.5% (95% CI, 33.0%-45.8%). Right: area under the curve (AUC) by receiver operating characteristic for 6-month NRM. (B) Validation set. Left: clinical responders: 10.3% (95% CI, 6.6%-15.0%), clinical nonresponders: 37.7% (95% CI, 27.8%-47.6%). Middle: MAGIC composite responders: 6.9% (95% CI, 4.0%-11.0%), MAGIC composite nonresponders: 45.8% (95% CI, 35.3%-55.8%). Right: AUC by receiver operating characteristic for 6-month NRM. Pie charts depict percentage of responders/nonresponders.
