Generated Narrative: CodeSystem KGGradeCertainty

This case-sensitive code system http://smart.who.int/base/CodeSystem/KGGradeCertainty defines the following codes:

Code	Display	Definition
high	High	We are very confident that the true effect lies close to the estimate of the effect.
moderate	Moderate	We are moderately confident in the effect estimate: the true effect is likely to be close to it, but there is a possibility that it is substantially different.
low	Low	Our confidence in the effect estimate is limited: the true effect may be substantially different from it.
very-low	Very low	We have very little confidence in the effect estimate: the true effect is likely to be substantially different from it. Not the same finding as 'could not determine' — absent evidence is a gap, not a grade.
