Fig. 3: In SMM patients (n = 184), the first sBCMA sample collected was used to stratify patients into two groups, those with sBCMA below versus above the median sBCMA at first sample collection.
From: Serum BCMA levels predict outcomes in MGUS and smoldering myeloma patients

The A PFS, and B OS are shown, stratified by the median sBCMA values at first collection.
