What was measured

Primary Outcome 2: To assess whether the novel magnetic resonance (MR) protocol and exploratory bone turnover markers can improve quantification of bone loss in patients with myeloma (new, relapsed, smouldering) and Monoclonal Gammopathy Of Uncertain Significance (MGUS) at baseline assessment, compared to Dual-energy X-ray Absorptiometry (DXA) and established bone turnover markers alone. This particular section analysed the inter-group difference in baseline serum CTX-1 (Collagen Cross-Linked C-Telopeptide Type I) bone turnover marker levels, in patients from Groups 1a (new myeloma), 1b (relapsed myeloma), 1c (smouldering myeloma) and 2 (MGUS).

Analysis population: All participants recruited at baseline from Groups 1 and 2 who had successful measurement of baseline serum CTX-1.
