Similarly, SOD activity showed highly significant differences between groups, both in GCF (F = 15.66, p < 0.001, η 2 p = 0.177) and in plasma (F = 20.94, p < 0.001, η 2 p = 0.223).

In plasma, MDA levels were marginally higher in leukemia children compared to controls (F = 3.33, p = 0.072, η 2 p = 0.044), suggesting a near-significant trend at the 10% level.
The GLM analysis also showed that three interaction effects reached marginal significance at the 10% threshold, suggesting possible moderating influences between local oral parameters and demographic factors ( Table 8 ).
When the overall multivariate test was significant or marginally significant, individual univariate GLMs were examined to identify specific effects on each biomarker.
