Table 3.

CS As a Function of Age and VA for Each Diagnosis

Diagnosis	N	Regression Models*
Cataract	899	CS = 1.88 – 0.004 × Age – 0.22 × VA (R2 = 0.22)
AMD	353	CS = 1.81 – 0.004 × Age – 0.63 × VA (R2 = 0.47)
Glaucoma	196	CS = 1.83 – 0.004 × Age – 0.39 × VA (R2 = 0.29)
RP	153	CS = 1.67 – 0.004 × Age – 0.97 × VA (R2 = 0.60)

^*Each equation is derived from the best model fit to the data.
