Receiver operating characteristic analysis on the active voxels in the spinal cord

Type of Map	Sensitivity	Specificity	AUC	P
No correction	0.616	0.649	0.577	0.128
Only cardiac noise correction	0.808	0.765	0.859	0.003 *
Only respiration noise correction	0.861	0.843	0.936	0.001 *

The activation map with both cardiac and respiration correction was selected as the ground truth, and the three other maps were compared against it; AUC: Area under the curve;

^*Demonstrates significant value (P<0.05).
