Correction to: Revised free light chain reference intervals enhance risk stratification in monoclonal gammopathy of undetermined significance and reduce overdiagnosis (Blood Cancer Journal, (2025), 15, 1, (80), 10.1038/s41408-025-01289-7)

Correction to: Blood Cancer Journalhttps://doi.org/10.1038/s41408-025-01289-7, published online 28 Apr 2025 In this article the formatting of table 3 was not correct. In table 4 a correction typing mistake of total number 6881. Table 3 Free light chain ratios and progression risk (Table presented.)
