Medians (IQR) are listed for the continuous and the proportions (%) are for the categorical variables.
*
p-values are from the Wilcoxon rank sum for the continuous variables, and a χ2 test for differences in proportions. VH = visual hallucinations (probable and definite combined together). RBD = probable REM-sleep behavior disorder, SUVR=Standardized uptake value ratio.
