Linear mixed effects on hypothalamic microstructure (neurite density index (NDI), orientation dispersion index (ODI), free water fraction (FWF), and effective transverse relaxation rate (R2*)) between subunits (anterior-inferior (A-Inf), anterior–superior (A-sup), intermediate (Int), posterior (Post)) and across age while controlling for sex.
