Effects of covariates on circRNA expression. a Distribution of the mean expression of each circRNA in exonic, intronic, and intergenic regions. The black dashed line indicates the cumulative data fraction. b Differential circRNA expression detected as a function of age of death. The dots in red indicate significantly differentially expressed circRNAs (FDR ≤ 0.05). c CDR1as expression with age of death is plotted. d Boxplot for the expression of gender-related circRNA (chr9:44106654|44114921) from a pseudogene, ANKRD20A7P. The center line denotes the median, the limits are the interquartile range (IQR), the whiskers are 1.5× the IQR, and outliers are shown as black dots
