Summary of circRNA prediction results. a Number of unique and common circRNAs in AD and ND PC. b Read count distribution of all detected circRNAs. c Intersection of circRNAs called by the four tools; the red bar indicates the number of circRNAs called by all four tools d Size distribution of all detected circRNAs. e Violin plots indicating the number of circRNAs predicted by each tool across PC samples along with the probability density. f Number of circRNAs predicted by each tool across PC samples, condition-wise. AD, Alzheimer’s disease; ND, no disease; circRNA, circular RNA; PC, posterior cingulate; bp, base pairs
