Paired comparison using the Wilcoxon signed-rank test (non-parametric) showed a strong trend toward higher CD34 expression in the subumbilical region, reaching the limit of statistical significance (U = 5.0, p = 0.0518).
Paired comparison using the Wilcoxon signed-rank test (non-parametric) showed a strong trend toward higher CD34 expression in the subumbilical region, reaching the limit of statistical significance (U = 5.0, p = 0.0518).
In contrast, CD34 displayed higher sub-umbilical scores (median 3) compared with supraumbilical (median 2), with a strong trend toward significance ( p = 0.052) and a large effect size, suggesting increased microvascular density/activation in the sub-umbilical segment.
These findings suggest a trend toward increased DUX4 expression in the subumbilical region, although this did not reach statistical significance.
