For the consensus, defined in category 2B, a panel vote of at least 50% (but < 85%) is required. Lastly, for recommendations where there is a strong panel disagreement regardless of the quality of the evidence, it requires a panel vote of at least 25% to include and designate a recommendation as category 3
