Added following statement at the top of the page: 

March 2020: This policy was developed in 2014 and applies to all Cochrane Reviews until the launch of the new Cochrane Conflict of Interest Policy for Cochrane Library Content, which is planned for July 2020. After the launch of the 2020 policy, the policy set out below will still apply to the following content: protocols being prepared based on new titles registered before the July launch date; protocols for Cochrane Reviews already in progress before the July 2020 launch date; and Cochrane Reviews (including updates) in progress before the July 2020 launch date.
