Erosive progression over time was analysed in patients with and without anaemia,¹¹ (A,B) without NSAID and (C,D) with antitumour necrosis factor-α therapy. Values are mean and 95% CI. The progression of erosions (mean±95% CI) was adjusted for potential confounders (figure 1, table 1). Patient numbers at given time points are the same in left (A,C) and right hand figures (B,D).
