Correlation between FD parameters and highest CNV flow or CNV flow thickness were performed with Spearman rank correlations reported with r and P values. Correlation between FD parameters and the categorical value of number of flow layers were performed with the Kruskal–Wallis H test (one-way ANOVA on ranks) with P value reported. If the Kruskal–Wallis was significant, post hoc Dunn tests were reported for individual comparisons between layers with pairwise z test statistics and P values. The MFDS is reported as diameter in microns.

P < 0.05.
