Fig. 3From: Easy and effective test to evaluate tear-film stability for self-diagnosis of dry eye syndrome: blinking tolerance time (BTT)Receiver operating characteristic (ROC) curve of tear breakup time without anesthesia (TBUT[BE]) and the BTT. The area under the ROC curve (AUC) of the tBUTBE was 0.678 and the AUC of the BTT was 0.628. The difference between these 2 AUC values did not reach statistical significance (p = 0.641)Back to article page
