The German League Against Rheumatism (Deutsche Rheuma-Liga) strongly supports the All trials Initiative. As a patient organisation with over 270.00 members we plead for full disclosure of all clinical trial results. To date, we have no cure for rheumatic diseases. Only if we know about all negative as well as positive outcomes and can make treatment decisions based on the best evidence possible, we have the chance to support people with rheumatic diseases with the best medical care.
