Etanercept is Effective and Halts Radiographic Progression in Rheumatoid Arthritis and Psoriatic Arthritis: Final Results from a German Non-interventional Study (PRERA).

This was the first real-world, non-interventional study to report systematically collected radiographic data in a large cohort of patients with RA or PsA under treatment with a biologic. In patients with available radiographic data, mean radiographic progression was lower and the proportion of patients without progression was greater during ETN treatment than in the pre-ETN period.
