Figure 1b. Positional variance diagram for the vision subgroup showing the uncertainty in the progression of volume loss (biomarkers on y axis) across different stages (positions on x axis). Each entry (x,y) represents the probability of region y becoming abnormal at position x in the sequence, ranging from 0 in white to 1 in black. Ram J. Bishnoi, Sandarsh Surya, W.
