Tracts in which reduced FA was correlated with increased levels of depression in those with high CPO; FWE -corrected threshold of P <  0.05. a) Results (red-yellow) are projected on a white matter skeleton (green), overlaid on a customized mean FA image. b) FA as a function of HADS depression (lower scatterplots), conditional on CPO (upper panel). The upper panel depicts the overlapping ranges of CPO that determine the subsample of each scatterplot. A linear regression line was fit for each scatterplot to aid interpretation.
