Table 4. Sensitivity and specificity metrics for each of the Receiver Operating Characteristic curves.
Sensitivity (%) | Specificity (%) | AUC | Optimal cut-off | p-value | |
---|---|---|---|---|---|
Dim Mean CV | 92.86 | 75 | 0.85 (.09) | 2.26 | .002 |
Dim Max CV | 92.31 | 66.67 | 0.79 (.10) | 4.11 | .015 |
Bright Mean CV | 100 | 66.67 | 0.87 (.08) | 2.45 | .002 |
Bright Max CV | 69.23 | 91.67 | 0.85 (.08) | 4.93 | .003 |
Optimal cut-off scores and associated sensitivity/specificity calculated using a pre-test probability of 50%, and a cost-ratio of 1. Error for AUC values denoted as standard error.
