The differences in EA‐CSF ratio between groups remained highly significant ( F 1, 49 = 37.16, p < 0.0001), and the group differences in TCV ( F 1, 49 = 198.63, p < 0.0001) and EA‐CSF volumes ( F 1, 49 = 0.16, p = 0.69) were consistent with the original analyses, confirming the robustness of our findings.
