Regression model predicted wgaDNA concentrations and GCR by storage year. The predicted effect of the year of initial storage on the GCR in the three case-control studies (blue: 610k; green: Axiom; red: Omni19) are shown on the primary (left) y-axis. The secondary (right) y-axis shows the predicted wgaDNA concentration (purple line) over the year of initial storage.
