Scatterplot depicting the positive correlation between average gene expression values of upregulated genes in Figure 6B and Alu RNA processing ratio in AD patients (r = 0.88, p<0.001). 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. Scatterplot depicting the negative correlation between average gene expression values of down-regulated genes in Figure 6C and full length Alu RNA levels in AD patients (r = -0.42, p<0.001). Statistical test as in subfigure 6D.
