Effect of years of storage on wgaDNA concentration. The X-axis represents the year of initial storage of DBS sample, and the y-axis shows the wgaDNA concentration in ng/uL. Black dots represent outlier values, and the adjacent lines the upper and lower adjacent values. The upper and lower hinges represent the75th and 25th percentile values, respectively, and median values are marked inside the box.
