Correlation between gene expression and Alu RNA processing ratio for AD upregulated genes (Dataset EV3) (upper panel) and a random set of non-differentially expressed genes (Dataset EV5) (lower panel). For every gene a correlation coefficient was calculated (Pearson correlation) together with the respective p-value. Statistical test is based on Pearson's product moment correlation coefficient and follows a t distribution using the cor.test function in R package stats. Based on the r and p value genes were classified into four categories: i) NS, non-significant for p value > 0.05, ii) no correlation or weak correlation (r≤0.05), iii) significant (p < 0.05) and strong correlation (0.5
