The correlation analysis on dry eye examinations. A Meibomian gland dropout of upper eyelid had negative correlation with fluorescein break-up time and average noninvasive keratograph tear film break-up time (R = -.227, P = .033; R = -.268, P = .012), but no correlation with first noninvasive keratograph tear film break-up time (R = -.020, P = .854). B In Sjögren’s Syndrome Dry Eye patients, OSDI had a negative correlation with fluorescein break-up time (R = -.749, P<.001) but no correlation with both first noninvasive keratograph tear film break-up time and average noninvasive keratograph tear film break-up time (R = -.029, P = .851 and R = -.060, P = .700). C In non-Sjögren’s Syndrome Dry Eye patients, OSDI had a negative correlation with fluorescein tear film break-up time and average noninvasive keratograph tear film break-up time (R = -.705, P<.001; R = -.531, P<.001), but no correlation with first noninvasive keratograph tear film break-up time (R = -.128, P = .408)
