Figure 1: Receiver operating characteristic (ROC) curve of MQ, OSDI, and SEEQ. The area under the ROC curve (AUC) ranged from 0.89 to 0.92. MQ had the largest area, 0.92. When the cutoff value for abnormal MQ was 15, good diagnostic accuracy was obtained with 75.5% sensitivity and 93.9% specificity. MQ: McMonnies Questionnaire; OSDI: Ocular Surface Disease Index; SEEQ: Salisbury Eye Evaluation Questionnaire.
