Figure 8.

Capillary density was plotted against microaneurysm count in each of the four study regions. A regression line was fitted for each region. Both the 3-mm (P = 0.040) and 6-mm (P = 0.007) regions had significant associations between microaneurysm number and capillary density. The parafovea region exhibited a steep regression line, however, the association did not reach statistical significance (P = 0.051). In the 9-mm region, capillary density was also not associated with microaneurysm frequency (P = 0.408).
