The multivariable analysis confirmed the independent prognostic value of the following factors: MM with a monoclonal component (HR = 0.30; p = 0.076), low albumin levels (HR = 3.14; p = 0.0006), and CC genotype of IL1B gene (rs1143634) (HR = 2.03; p = 0.0337). Here, ALB is linked to Miyoshi myopathy.
