Table 2 Models for the association between age and weight with mean blood flow.

From: Retinal blood flow association with age and weight in infants at risk for retinopathy of prematurity

Mean BFV = [intercept] + 1.2084 Current weight (in kg)

p = 0.0280

Mean BFV = [intercept] + 0.3382 Current age (in weeks)

p = 0.0004

Mean BFV = [intercept] + 0.3640 Post menstrual age (in weeks)

p = 0.0007

Mean BFV = [intercept] − 0.3522 Birthweight (in kg)

p = 0.8160

Mean BFV = [intercept] − 0.1766 Gestational age (in weeks)

p = 0.3841

  1. Analysis used mixed models to simultaneously account for the inclusion of both eyes per subject, and the inclusion of repeat measures of the same eye (n = 91 eye exams). Bold indicates p < 0.05.
