MM characteristics depending on the protein level. (A) Age of the MM patients at diagnosis depending on the level of PSDM10-gankyrin and GCR proteins. The P value is that corresponding to a Mann-Whitney U test. (B) AGO2 level association with LDH. The P value indicates the level of significance of the χ² statistic. (C) Cereblon protein level at diagnosis and association with plasmacytoma occurrence. The P value indicates the level of significance of the χ² statistic. (D) Association between IRF4 and PSMD4 protein levels with cytogenetic risk group. The P value indicates the level of significance of the χ² statistic. (E) Hemoglobin level at diagnosis in MM with high and low levels of IRF4 and PSME1 protein expression. The P value is that corresponding to a Mann-Whitney U test.
