Curves that approach closest to the co-ordinate (x=0, y=1) are more highly predictive, whereas ROC curves that lie close to the line of equality indicate that the result is no better than that obtained by chance. The optimum sensitivity and specificity can be determined from the graph as...

Figure2depicts receiver operating characteristic (ROC) curves, and the corresponding areas under the ROC curves (AUC) for the twelve different models of ICH detection. Models trained on fully sampled images had AUCs of 0.898 in image-space (I1), 0.918 in sinogram-space (S1), 0.972 in windowe...

Four independent datasets (892 women) were used in the validation portion of the study.Main Outcome Measures. Diagnosis of HSDD was clinician-derived. Receiver-operator characteristic (ROC) curves were used to develop the cutpoint, which was confirmed in the validation dataset.Results. The use of...
of 50–69%, which had a sensitivity of 93%, specificity of 68%, and overall accuracy of 85%. A PSV of ≥230 cm/s for ≥70% stenosis had a sensitivity of 99%, specificity of 86%, and overall accuracy of 95%. ROC curves showed that the ICA PSV was significantly better than EDV ...
Accuracy of radiograph interpretation was measured as the area under the physicians' receiver operating characteristic (ROC) curves. The area under the ROC curve was 0.15 (95% confidence interval [CI], 0.10-0.20) greater for radiologists than for emergency medicine physicians, 0.07 (95% CI, 0.02...
The use of a statistical technique for paired comparisons using receiver operating characteristic (ROC) curves is illustrated by studying the extent to which clinical history altered the interpretation of computed tomographic (CT) examin... Barbara J Mcneil,A James,Hanley,... - 《Radiology》 被引...
We firstly tried to optimize the length of the input sequences according to AUCb(b stands for binary). AUCbis the area under ROC curves calculated based on the positive and the corresponding negative samples (e.g., A for m1A) of each modification. Using the Word2vec embedding, we evalua...
Comparison of ROC curves demonstrated that this five-strata approach is statistically more accurate than current accepted practice at discriminating whether patients have HIT or not (area under the ROC curve, 0.97 [95% CI, 0.93-1.00] vs 0.83 [95% CI, 0.80-0.89]). Our decision-support ...
