Linear regression analysis. Regression results for two representative regions of interest are reported, one resulting as activated in the general linear model analysis for task 1 in patients with essential tremor (right pre/postcentral gyrus [PRG.r/POG.r]) and one as deactivated (left posterior cingulate gyrus [CGp.l]). Individual BOLD results, expressed as z-statistic values, were linearly regressed against the Fahn–Tolosa–Marin Tremor Rating Scale (TRS), part A + B. The correlation value (r-value) and the corresponding false-discovery rate (FDR)-corrected p-value (pFDR) are also reported.
