Table 6.

Generalized Linear Model (type III Sum of Squares) for variables explaining size class, now incorporating cataract incidences between ages 7 and 10, as well as for age 7 and above

Variable	F Value	P Value
% Dogs seen >10 years	22.65	<0.0001
Incidence 4 to 5 years	0.02	0.8751
Incidence 7 to 10 years	3.22	0.0773
Incidence >7 years	8.45	0.0050
Lifetime Incidence	12.62	0.0007

There are five degrees of freedom. Coefficient of determination (R²) = 0.45, P_Model <0.0001
