Figure. Receiver Operating Characteristic Curves of the 5 Validated Dry Eye Symptom Questionnaires.

Receiver operating characteristic curves of the discriminative ability of the Ocular Surface Disease Index (OSDI), 5-Item Dry Eye Questionnaire (DEQ-5), McMonnies Dry Eye Questionnaire (McMonnies), Symptom Assessment in Dry Eye (SANDE), and Standard Patient Evaluation of Eye Dryness (SPEED) questionnaires in detecting objective signs of dry eye disease. The dotted line represents the diagonal line of no discrimination or random chance. The magnitude of the area under the curve indicates the discriminative ability of each individual symptom questionnaire in detecting clinical signs of dry eye disease.
