Figure 4.

Box and whisker plots showing vessel area measurements in different subgroups of patients. Each box indicates mean (cross within the box), median (central horizontal line), and IQR (horizontal extremes of the box) values for a specific variable at each visit. The minimum and maximum values correspond to the ends of the whiskers. Dots indicate outliers. On the y axis, values are reported in square micrometers. The values at different visits are arranged along the x axis, with category labels provided in the legend in the upper left corner. Each row corresponds with a different region: (i) GA region (top row), (ii) 150-µm-wide border around the GA (middle row), and (iii) the area beyond the border (bottom row). Each column represents a different group: the left column displays values from the group where the GA border exhibited no RPE atrophy at baseline but progressed into GA at the 6-month follow-up, whereas the right column contains data from cases where the border did not transition into GA during the follow-up period. Additional details regarding pairwise comparisons can be found in Tables 2 and 3.
