Figure 1From: Effect of prednisone on type I interferon signature in rheumatoid arthritis: consequences for response prediction to rituximab Effect of prednisone use on IFN-score in cohort I. In peripheral blood of 32 RA patients, gene expression levels of 7 interferon response genes were averaged to calculate the IFN-score. The IFN-score was evaluated in relation to prednisone use; prednisone-treated patients (PREDN+) exhibited a lower IFN-score than prednisone-untreated patients (PREDN−).
