HLA-G and plasma cell myeloma: Univariate analysis showed that β2-microglobulin (odds ratio (OR), 24.3; P = 0.003) and BMPC% (OR, 7.00; P = 0.02) was significantly higher, whereas fat-signal fraction (OR, 9.00; P = 0.002) and hemoglobin (OR, 38.00; P = 0.001) were significantly lower in symptomatic myeloma than in asymptomatic myeloma.
