ROC curve analysis for different ALFF areas between RRMS and HCs
| Regions | ROC curve
|
|||
|---|---|---|---|---|
| AUC | Sensitivity (%) | Specificity (%) | Cutoff point of mean ALFF value | |
| Fusiform gyrus | 0.886 | 77.8 | 88.9 | −0.6716 |
| Pons, brainstem | 0.784 | 66.7 | 100 | 1.9603 |
| Caudate head | 0.877 | 83.3 | 83.3 | 0.02545 |
| Anterior cingulate gyrus | 0.901 | 88.9 | 77.8 | 0.2526 |
Note: All areas had high AUC values and exhibited high degrees of sensitivity and specificity.
Abbreviations: ALFF, amplitude of low-frequency fluctuation; AUC, area under the curve; HCs, healthy controls; ROC, receiver operating characteristic; RRMS, relapsing–remitting multiple sclerosis.
