Figure 3 ROC curve between group IIA and IIB regarding RDW. RDW at level 14.5% can differentiate BTT from IDA with 83.3% sensitivity and 100% specificity of the test. BTT, β-thalassemia trait; IDA, iron deficiency anemia; RBC, red blood cell; RDW, red blood cell distribution width; ROC, receiver operating characteristic.
