However, the non-parametric Kruskal–Wallis test, applied for the comparison of all three groups, identified a highly significant overall difference (χ 2 = 13.56, df = 2, p = 0.001136).

In summary, while methylation at the CPG1 site of DKK1 gene did not distinguish the patient cohorts from the healthy controls, it revealed a nominally significant epigenetic discrepancy. between the two clinical phenotypes, with the comorbid osteoporosis and osteoarthritis group exhibiting elevated methylation relative to the group with OA alone.
Similarly, the comparison between the two patient groups (OP+OA versus OA without OP) failed to reach statistical significance after correction (p adj = 0.065).
