Association of diagnostic status with the T1w/T2w ratio in parcels selected by elastic net. A) The t-statistic for the association of unipolar depression (UD) with T1w/T2w ratio in the n = 33 selected parcels. Regions where individuals with UD had a greater average T1w/T2w ratio than HC are in red, and regions where HC had a greater average T1w/T2w ratio than individuals with UD are in blue. B) The percent of models in which each parcel was retained. Regions are individually labeled (note that FFC is not visible, as it lies on the ventral surface). (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
