Frequently misdiagnosed disorder symptomatology

Core findings in the frequently misdiagnosed group of disorders PD, PDD, DLB, MSA and PSP. Overview of signs and symptoms that are significantly enriched in only one disorder (top) and overview of signs and symptoms that are not significantly enriched in one disorder (bottom). An attribute was significant when it was more commonly observed than expected given a random background distribution. The random background distribution was calculated by randomly permuting the diagnosis labels of the individual donor data with 100,000 permutations. The P value was calculated as the proportion of observations in which the observed value was higher than the random background and was multiple testing corrected using the Benjamini–Hochberg FDR.
