Figure 5.

Strength of evidence for the association between superior and inferior BV locations on the four concentric circles around ONH (black curve with circle point: arteries and magenta curve with square point: veins). Blue shaded area indicated by the annotation “positive” and “strong” in the lower plot region below zero horizontal axis illustrates the area of evidence for the null hypothesis H₀ that superior and inferior BVs are unrelated. Red shaded area indicated by the annotation “positive” and “strong” in the upper plot region above zero horizontal axis illustrates the area of evidence for the alternative hypothesis H₁ that superior and inferior BVs are related. White area illustrates the area of evidence strength that both H₀ and H₁ models are not preferred over their counterpart alternative model.
