Figure 4.

Paired abundance data for all signatures with differential expression significant at p < 0.05. Each data point corresponds to a signature with expression that is significantly different between the N/40 and P/40 libraries at p < 0.05. Data are plotted as signature expression in the P/40 library (x-axis) vs. expression in the N/40 library (y-axis). The axis scale decreases from left to right panels to show detail. Dashed line is the line of constant expression, i.e. the point at which the expression ratio is two-fold different between the two conditions.
