Fig. 2From: Extracellular matrix turnover biomarkers reflect pharmacodynamic effects and treatment response of adalimumab in patients with axial spondyloarthritis—results from two randomized controlled trialsThe pharmacodynamic effect of ADA treatment in the DANISH and ASIM studies. Percentage (%) change from baseline of the placebo group vs the ADA group of the selected ECM biomarkers. A.1–G.1 DANISH study. A.2–G.2 ASIM study. p-values at weeks 12 and 6 were adjusted for multiple comparisons by the false rate discovery method, and a significant difference is displayed by the following asterisks: *p < 0.05, **p < 0.01, ***p < 0.001. Dashed points determine the crossover from placebo to active ADA treatment. Data are presented as mean ± standard error of the mean. Only biomarkers that obtained significance in the analyses are shown here; the rest are provided in Additional file 1: Fig. S1.
