AUC-ROC curves of the 4 chilled to ambient hand ratios derived from the 99mTc-HDP radioactivity curve of patients with Raynaud’s phenomenon and controls.

AUCSE (95% CI)
Initial slope ratio0.9680.014 (0.941, 0.995)
First peak height ratio0.9580.016 (0.926, 0.989)
30-second AUC* ratio0.9330.022 (0.890, 0.977)
Blood pool uptake ratio0.9400.020 (0.901, 0.978)
  • AUC-ROC: area under the receiver-operation characteristic curve.

  • * AUC: area under the radioactivity curve. See Figure 1B.
