Accepted methods are used to develop reference standards so that clinically relevant, well characterised data is collected and the limitations of the reference standard are understood; the choice is documented against the intended use and assessed for suitability in the intended use environment, accepted reference standards that demonstrate robustness and generalisability are used where available, and selection rests on broad consensus and appropriate expertise.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
