(A) Locally weighted regression lines illustrating the independent relationship between level of spherical equivalent refractive (SE) error ; (B) or absolute cylindrical power (astigmatism) and the estimated prevalence of bilateral decreased visual acuity (VA) in preschool children in the Multi-Ethnic Pediatric Eye Disease Study (MEPEDS) and the Baltimore Pediatric Eye Disease Study (BPEDS) after controlling for other risk factors. The estimated prevalence of having any bilateral decreased VA was obtained using the stepwise logistic regression procedure. The plot for Figure 3a excludes 2 children with highly hyperopic refractions (>11.00 D SE in both eyes) due to aphakia. VA: visual acuity. SE: spherical equivalent.
