Box plot of AF hyperfluorescent ring annulus at baseline, 6, and 12 months. The plots represent the median, interquartile range, and maximum range of values. The range is large due to participants' covering a spectrum of disease severity. Kruskal-Wallis ANOVA testing showed no significant difference between the time points (P = 0.93), but the medians showed a trend for a decrease in the hyperfluorescent ring diameter between 0 and 12 months.
