  1. Ϯ Most trials did not identify the literacy level of the intended audience. We operationalized this criterion to code “present” if the research sample group’s literacy requirements were stated.
  2. ϮϮIf the PtDA was text based, but included graphics of frequencies and other numeric data, these were considered to be text. This criterion was meant to provide for alternative media for non-readers such as pictures, video explanations of data, voice-over narration, etc.
