Unavailable values are not missing at random. The bars show the average observed mRNA levels (left panel) and protein concentration values (right panel), standardized, plotted as a function of the number of missing values for each mRNA (out of 38 total), or protein (out of 20 total). Bar widths are proportional to the number of genes (proteins) in each bin.
