Figure 3.

Boxplot showing the relationship between reported hours of patching in the first year of life and between 12 and 48 months of life and optotype visual acuity at 4 ½ years of age in the Infant Aphakia Treatment Study.

The boxes represent the interquartile range (i.e., 25^th percentile to 75^th percentile) of visual acuity associated with each combination of patching in the 1^st year of life and patching between 12 and 48 months of age, with the whiskers representing the full range of vision excluding any outliers which are shown as circles. The center line indicates the median visual acuity.
