↵a Dichotomous outcome measures are presented as percentages (number of correct responses out of 204 total responses per session). Continuous outcomes are presented as means (SD). Odds ratios, regression coefficients (B), Z-tests, and P-values from the regression analyses are also presented. CSQ = consultation satisfaction questionnaire. EHR = electronic health record. OR = odds ratio. SD = standard deviation. VAS = visual analogue scale.
