From: Global longitudinal strain as an Indicator of cardiac Iron overload in thalassemia patients
Receiver-operating characteristic (ROC) curves for global longitudinal strain (GLS) and magnetic resonance imaging (MRI) T2* value above 20 milliseconds from below 20 milliseconds as an indicator of cardiac iron deposition. As is shown taking a GLS below −19.5% as the threshold could predict a T2* level below 20 milliseconds with a sensitivity of 82.14% and specificity of 86.36% (area under the curve [AUC] = 0.87, p < 0.0001
