Speed of Retinal Vascularization in Retinopathy of Prematurity: Risk and Protective Factors

Table 1

Univariate analysis of factors that modify significantly the retinal vascular development: intubation days (d), BPD 3, weight gain at 4-6 weeks (gr/days), avascular temporal area (DD), gestational age (weeks), sepsis, apnea at birth, ductus arteriosus, and CPAP therapy (days).
