“B” and “R” represent the 2 factors that varied in our design. “B” represents the belief in OLP factor and “R” represents the responsiveness (improvement) factor. When preceded by a “+,” the “B” indicates a participant read a vignette wherein the patient did believe in the OLP treatment. A “−” symbol preceding “B” indicates that the patient did not believe in the OLP treatment. This same convention applies to the “R.” For example, the “OLP −B/+R Group” column is summarizing the sample characteristics of participants who read about a patient who did not believe in the OLP treatment but did report improvement at the 2-week follow-up.
