PRS distribution by MM, MGUS, and controls. This figure shows the PRS distribution by case-control status while indicating the median PRS for each group. InterLymph controls (median, 3.Array controls (median, 3.03) are in green, MGUS (median, 3.19) is in dark blue, and MM (median, 3.21) is in light blue. The distribution for both MM and MGUS are shifted to the right compared with the controls, and both have a higher median PRS score. There is no difference in the distribution of PRS for MGUS vs the MM cases (P > .05, Wilcoxon-rank-sum test).
