We observed significant changes in the mean albumin level of MG patients from 3.3 [SD 0.9] g/dl at baseline to 3.9 [SD 0.8] g/dl 6 months later while the mean albumin level of patients in the CG remained the same (3.9 [SD 0.7] g/dl) (P = 0.012) (Table 5). This evidence concerns the gene ALB and myasthenia gravis.
