Evaluation of the economic impact of modified screening criteria for retinopathy of prematurity from the Postnatal Growth and ROP (G-ROP) study

To determine the incremental cost-effectiveness of screening with G-ROP compared with conventional screening. We built a microsimulation model of a 1-year US birth cohort
