ROC曲线评估双参数与多参数的VI-RADS评分系统在膀胱癌中的诊断价值

Index	AUC of radiologist 1 (95% confidence interval)	AUC of radiologist 2 (95% confidence interval)
AUC: area under the curve; the other abbreviations are explained in the note to Fig 1.
mp-MRI	0.878 (0.830-0.925)	0.856 (0.805-0.907)
bp-MRI	0.889 (0.844-0.934)	0.856 (0.805-0.907)
