Primary outcomes

Opinion about result

Time frame: Immediately after the intervention

Participants' views about the results presented in different units. The exact question wording is: "In your view and based only on the information you have, what is your opinion of this result?" Participants indicate their response on a visual analog scale (a slider) from 0 to 100 with labels "It is not a problem at all" = 0, "I don't know" = 50, or "It is a big problem" = 100.
