Scatterplots illustrating the linear associations between flow density (FD) on OCT angiography, the disappearance angle of the RPCs (DA), and other factors in glaucoma.

<p>The correlation between FD, DA, and other factors was analyzed, and measurement data are shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0184301#pone.0184301.g003" target="_blank">Fig 3A–3C</a>. A scatterplot of FD and DA (y-axis) and the retinal nerve fiber layer defect (NFLD) angle (NFLD-A), circumpapillary RNFL thickness (cpRNFT), pattern standard deviation (PSD), mean deviation (MD), and threshold of sensitivity (TS) (x-axis) was generated to calculate a correlation coefficient. Only data with significant correlations are shown. r = correlation coefficient from the fitted linear regression model.
