Latent variable scores and mean caudate DaT binding.
The table shows associations of the PLS latent variables (LVs) extracted during the dimensionality reduction step with nigrostriatal dopaminergic function measured by 123I-FP-CIT SPECT (mean caudate SBR ratios). Positive significant associations (depicted in red) were found for LVs I (“global/motor”) and III (“executive”).
