FIGURE 2.

Association between retinal vessel skeleton density (VSD) and cognitive dementia rating sum of box score (CDR‐SOB). (A) Plot of VSD against crude CDR‐SOB scores. Small amounts of random vertical noise up to 0.05 units were added to the vertical axis to reduce the extent of overlap. (B) Box (25th–75th percentile) and whisker (5th–95th percentile) distribution of VSD versus CDR‐SOB after binarization. (C) Distribution of the proportion of subjects with CDR‐SOB >0 based on 0.01‐unit binning of VSD. (D) The odds ratio of having CDR‐SOB > 0 based on a tertile binning of VSD
