Corrected gestational age-specific prediction models for identifying treatment-requiring retinopathy of prematurity.

To develop and validate time-updated, corrected gestational age (corrected gestational age)-specific prediction models for identifying treatment-requiring retinopathy of prematurity (retinopathy of prematurity) using routinely available systemic factors, and to assess longitudinal changes in predictor combinations and model performance with advancing corrected gestational age.
