Figure 7. Fibrovascular tissue area (FA) values in the AOIs Figure 7.Fibrovascular tissue area (FA) values in the AOIs. For the intergroup difference between the TCP30 and the TCP70 groups, the Wilcoxon signed-rank test was used. For the intragroup difference among the five AOIs (anterior, posterior, window, center, and membrane), the Friedman test with post-hoc Dunn’s correction was used. *Statistically significant difference (p < 0.05).
