Table 1. Sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) for ROP diagnosis by 7 retinal fellows.^*.

Responses are compared to a reference standard of diagnosis by an expert pediatric retinal specialist. Analysis is performed by eye for diagnosis of mild or worse ROP, type-2 or worse ROP, and treatment-requiring ROP. Results are displayed as proportion (standard error), and unknown diagnoses by graders are considered incorrect responses.^†
