Whole-brain dopamine transporter binding pattern predicts survival in multiple system atrophy

For quantitative analysis, we then generated "relative decrease” maps for three clusters – cluster 1, 3, and 4, using cluster 2 as a reference cluster due to its relatively intact DAT binding (Fig. 1e). Multivariate survival analysis indicated that the cluster model (HR 2.00 [1.33–3.01], P = 0....

Description
Summary:For quantitative analysis, we then generated "relative decrease” maps for three clusters – cluster 1, 3, and 4, using cluster 2 as a reference cluster due to its relatively intact DAT binding (Fig. 1e). Multivariate survival analysis indicated that the cluster model (HR 2.00 [1.33–3.01], P = 0.001) and the BR of the brainstem (HR 0.07 [0.0083–0.63], P = 0.018) significantly predicted survival, with age, age at onset, sex, disease duration and disease subtype as cofactors (Additional file 1: The clustering model demonstrated independent prognostic predictive value, in contrast to traditional regional PET quantification parameters from the striatum, in predicting survival outcomes within the independent MSA cohort, as depicted in Table S5. [...]clinical rating scales like UMSAR (Unified multiple system atrophy rating scale) were not incorporated.
