Multiple linear regression model testing for interaction between the included variables: storage year (Year), storage conditions (Condition: +4°C vs. -20°C), type of filter paper (Filter Paper: S&S2992 vs. S&S903) and the wgaDNA concentration. Coef.: regression coefficient. 95%CI: 95% Confidence interval. Std.Err.: Standard error. A p-value of 0.000 is to be interpreted as being below 0.0001.
