I Graph of log10(mean) versus log10(CV2) of basal mRNA distributions measured in Jurkat T cells (black), HeLa cells (red) or murine bone marrow derived macrophages (green) for endogenous genes and four latent HIV LTR integrations. Gray shading indicates 95% CI of the linear regression for the basal trendline. Poisson trendline indicated by dashed line. HeLa data from Lee et al. (2014) and HIV LTR data from Wong et al. (2018).
