Summary of linear models involving intrinsic subregional thalamic microstructure predicting subregional thalamic volumes.

Subregion	Intrinsic factor	B (95%CI)	p‐value
Bilat. Pulvinar medial	Decreased subregional f is	0.75 (0.24; 1.27) [left] 0.85 (0.32; 1.38) [right]	0.005 0.003
	Increased subregional f ec	−1.10 (−1.42; −0.79) [left] −1.06 (−1.46; −0.66) [right]	2.69 × 10−8 5.00 × 10−6
R Mediodorsal medial	Decreased subregional f is	0.45 (0.20; 0.69)	6.77 × 10−4
	Increased subregional f ec	−0.64 (−0.89; −0.39)	7.30 × 10−6
L Anteroventral	Increased subregional f ec	−0.47 (−0.81; −0.12)	0.009
L Lateral geniculate	Increased subregional f ec	−0.40 (−0.58; −0.22)	6.79 × 10−5

Normalized volume of the following thalamic subregions could be predicted by either decreased intra‐soma signal fraction (f _is) or increased extra‐cellular signal fraction (f _ec) of the respective thalamic subregion: left and right medial pulvinar, right medial mediodorsal, and left anteroventral and lateral geniculate. Beta‐coefficients (B) with 95% confidence interval (CI) are reported with corresponding uncorrected p‐values surviving FDR correction.
