Collagen fiber alignment.

<p>Box plot of the average degree of fiber alignment in each of the 4 quadrants of the peripapillary sclera for normal, undamaged glaucoma, and damaged glaucoma specimens. The degree of fiber alignment was defined from the WAXS scatter intensity as the ratio of the aligned scatter to the total scatter (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0131396#pone.0131396.g003" target="_blank">Fig 3</a>). A scatter plot is superimposed to represent individual data points. Significant differences in degree of fiber alignment between two quadrants are indicated by connecting brackets (adjusted <i>p</i> ≤ 0.05).
