All codes in this table are from the system http://terminology.hl7.org/CodeSystem/reaction-event-certainty

unlikelyUnlikelyThere is a low level of clinical certainty that the reaction was caused by the identified substance.
likelyLikelyThere is a high level of clinical certainty that the reaction was caused by the identified substance.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
