    Validation of the adjusted multi-biomarker disease activity score as a prognostic test for radiographic progression in rheumatoid arthritis : a combined analysis of multiple studies 
    Curtis, Jeffrey R.; Weinblatt, Michael E.; Shadick, Nancy A.; Brahe, Cecilie H.; Østergaard, Mikkel; Hetland, Merete Lund; Sævarsdóttir, Sædís; Horton, Megan; Mabey, Brent; Flake, Darl D.; Ben-Shachar, Rotem; Sasso, Eric H.; Huizinga, T. W. (2021-01-04)
    BACKGROUND: The multi-biomarker disease activity (MBDA) test measures 12 serum protein biomarkers to quantify disease activity in RA patients. A newer version of the MBDA score, adjusted for age, sex, and adiposity, has been validated in two cohorts ...
