To further evaluate the potential prognostic value of SRSF1 in MM, age (≥65 vs. <65), gender (female vs. male), B2M (≥5.5 vs. <5.5), LDH (≥250 vs. <250), ALB (≥3.5 vs. <3.5), and lytic bone lesions on MRI (≥2 vs. <2) were enrolled in univariate and multivariate analysis. Here, ALB is linked to Miyoshi myopathy.
