Formulation of recommendations In drafting the recommendations, the WHO Steering Group used the summaries of evidence for the critical outcomes, quality of evidence, risks and benefits of implementing the recommendations, values and preferences, and costs. The draft recommendations, evidence summaries, GRADE tables and information on benefits and risks, values and preferences, and costs were presented to the GDG at its meeting held at WHO headquarters in Geneva, Switzerland, in September 2012. The GDG reviewed and discussed this information to finalize the recommendations. Individual members of the GDG filled in a worksheet to comment on the quality of evidence and the strength of each recommendation, before discussing these as a group. Where the GDG determined that there was insufficient evidence, consensus within the group was used as the basis of the recommendation.
