Associazione Alessandro Liberati – Network Italiano Cochrane strongly endorses the AllTrials initiative for all trials to be not just registered but also entirely published, to help patients, nurses, clinicians and policy makers make decisions based on all the best evidence. Openness is a value heavily defended by Alessandro Liberati, the founder of the Italian Cochrane Centre, and we are pleased to remember that openness contributes to strengthening the principles of democracy and respects for fundamental rights as laid down in Article 6 of the European Union treaty of Fundamental Rights of the EU.
