World Health Organization, 2011

The WHO Technical Consultation made a total of 23 recommendations. For each recommendation, the quality of the supporting evidence was graded as very low, low, moderate or high. Then, taking into account the quality of the evidence and other factors (including the values and preferences, the magnitude of effect, the balance of benefits versus disadvantages, resource use and feasibility of each recommendation), the experts marked the recommendations as either weak or strong following the GRADE methodology. In addition, in order to ensure that each recommendation will be understood and used in practice in accordance with its intended meaning, the experts made several remarks, which are noted below the recommendations in the full document.
