Guidelines Development Group
The GDG will follow the GRADE approach in defining the healthcare question of interest (population of interest, interventions to be compared and patient-relevant outcomes- PICO), synthesizing the evidence and developing the recommendations for the Guidelines. This will be carried out within virtual working environments and in meetings organised every three months.
An external contractor, CCIb –Iberoamerican Cochrane Centre, supports the GDG for their tasks from literature review to drafting of recommendations.
