摘要：Policymakers and researchers alike have called for a greater
focus on evidence-informed decision making.[1,2] For decisions
to be truly informed by scientific evidence, decision-makers
must continuously seek scientific advice as part of a well-functioning policy advisory system.[3] Scientific advisory committees (SACs) are often a critical part of this process, and offer
the potential of systematically identifying and assessing policy
options in light of the best available scientific evidence.[4,5] New
committees are constantly being created and old ones reformed
worldwide.[4,6] In fact, many countries routinely rely on expert
panels of various kinds to inform public policy.
