The percentage of dogs with 0,1, or > 2 ocular lesions was not significantly (P < 0.05) different between normotensive dogs and hypertensive dogs.

Sensitivity and specificity of the number of ocular lesions by type in the prediction of hypertension.

Values of ≥ 1 lesion.
NA = Not applicable. Normo = Normotensive dogs. Hyper = Hypertensive dogs.
