Likelihood Ratio Test as Fractional Anisotropy Reduction Relates to Changes in Mature Oligodendrocyte and Microglia Cells

	LRT	P Value	AUC	95%CI
All 7 WM regions (n=42)
Change in mature oligodendrocytes	10.03	0.002	0.800	0.652 to 0.951
Change in microglia cells	4.43	0.035	0.720	0.558 to 0.884
BCC, SFWM, MFWM (n=18)
Change in mature oligodendrocytes	24.73	<0.0001	1.000	0.998 to 1.000
Change in microglia cells	0.71	0.405	0.650	0.374 to 0.926

AUC indicates area under a quantity‐time curve; BCC, body of the corpus callosum; CI, confidence interval; FA, fractional anisotropy; LRT, likelihood ratio test from logistic regression; MFWM, middle frontal white matter; SFWM, superior frontal white matter; WM, white matter.
