TABLE 3.

Regression models on maximum reading speed, critical print size, and reading acuity with VA and CS as predictors.

	VA	CS	R2	Regression model
Maximum reading speed	F(1, 35) = 0.42, p = 0.52	F(1, 32) = 30.83, p < 0.001	0.25	Maximum reading speed=2.20 × (1– exp(−3.56 × (CS+0.40)))
Critical print size	F(1, 38) = 1333.47, p < 0.001	F(1, 34) = 88.78, p < 0.001	0.95	Critical print size=0.65 + 0.95 × VA - 0.21 × CS
Reading acuity	F(1, 35) = 1111.36, p < 0.001	F(1, 37) = 73.14, p < 0.001	0.96	Reading acuity=0.30 + 0.95 × VA - 0.21 × CS
