Figure 3. Retinal vessel densities by diabetic retinopathy (DR) diagnosis. Mean vessel densities are shown for each retinal area for each DR severity diagnosis. Error bars depict the standard deviations of the vessel densities. Asterisks indicate which retinal areas showed significant differences in vessel densities between DR severity diagnosis groups in multivariate regression analysis.
