Table 5. Comparison of sensitivity, specificity and area under the ROC curve between NIBUT and TBUT in the first, second and third measurement of the right eye in study patients.
| Sensitivity (%) | Specificity (%) | AUC | AUC | Sensitivity (%) | Specificity (%) | ||
|---|---|---|---|---|---|---|---|
| NIBUT 1st | 65.62 | 73.68 | 0.809 | 0.702 | 74.19 | 68.42 | TBUT 1st t |
| NIBUT 2nd | 74.19 | 89.47 | 0.855 | 0.701 | 77.42 | 78.95 | TBUT 2nd t |
| NIBUT 3rd | 70.97 | 83.33 | 0.818 | 0.722 | 77.42 | 84.21 | TBUT 3rd t |
AUC = area under the ROC curve; NIBUT = noninvasive break-up time; TBUT = tear break-up time
