nominally significantp = 0.033
Comparing MDD-SI and MDD-nSI, nominally significant group × time interactions were observed for the λ ( F = 4.530, p = 0.033; β = 0.725, 95% CI: 0.049 to 1.400), and nodal efficiency exhibited a nominally significant group × time interaction in the right posterior cingulate gyrus ( F = 3.958, p = 0.046; β = -0.783, 95% CI: -1.565 to -0.003).
