T2 signal ratios

	Mean (95%CI)
T2 signal ratio	GDM ≤26 group (n = 24)	GDM >26 group (n = 47)	No GDM group (n = 51)
MBH:AMY	1.25 (1.18–1.32)	1.18 (1.14–1.23)	1.19 (1.15–1.22)
MBH:WM	2.25 (2.11–2.38)	2.13 (2.06–2.20)	2.11 (2.05–2.18)
AMY:WM	1.80 (1.75–1.86)	1.80 (1.77–1.84)	1.78 (1.75–1.81)

Higher MBH:AMY or MBH:WM T2 signal ratios signify evidence of gliosis.
