miRNA profile for Parkinson's disease with dementia. (A) Line plot for the 125 DE miRNAs in PD. The counts were scaled using Z-transformation, and the means were calculated for each miRNA for each condition (control, PDN, PDD). The line colors correspond to the beta estimates from the ordinal regression analysis, where blue=negative ordered relationship and red=positive ordered relationship. (B) PDN/PDD class prediction, using the 36 nominally significant miRNAs from PDN/PDD differential expression analysis. Four errors were observed among the 29 samples studied which may reflect heterogeneity in the etiology of PD.
