Concurrently, a highly significant inverse correlation was observed between ROM and degeneration severity (W = 34.22, p = 0.0008).

While the global variance across all three Miyazaki grades (Welch’s ANOVA) exhibited a strong but marginally significant trend (W = 6.308, p = 0.0516), this is mathematically attributable to the restricted sample size of the Mild cohort ( n = 3), which diluted the omnibus statistical power.
Specifically, Dunn’s multiple comparisons test indicated that while the height loss score in the Severe group (2.700 ± 0) was numerically higher than that of the Mild group (1.667 ± 0.471), this pairwise comparison showed a strong trend but did not reach statistical significance (adjusted p = 0.0988), likely due to the conservative nature of the non-parametric test and the limited sample size in the Mild cohort.
