Fig. 4From: Role of interleukin-6 in ischemic stroke outcomeROC displaying specificity and sensitivity of IL-6 in predicting recurrence. Receiver operating characteristics (ROC) with area under the curve (AUC) analysis was used to test the specificity and sensitivity of IL-6 testing to predict recurrence. AUC value was 0.9 indicating both strong test specificity and sensitivity in predicting recurrence with a P value of < 0.0001Back to article page
