For the third metacarpal, the omnibus ANOVA approached significance (F(2,72) = 2.96, p = 0.058, η 2 = 0.076), with mean canal diameter increasing from 3.03 ± 1.10 mm (<30 years) and 3.05 ± 0.88 mm (31–50 years) to 3.71 ± 0.97 mm (≥51 years), suggesting a similar but less robust age-related widening pattern.

The comparison between the ≥51 years and <30 years groups showed a similar directional increase but did not reach statistical significance (mean difference = 0.69 mm, 95% CI −0.11 to 1.49 p = 0.096).

This near-significant finding may reflect a parallel anatomical aging process that did not reach sufficient statistical strength in the current sample.
