Impact of introduction format on the increase in cardiovascular activity from baseline to the video-vignette introduction (a) and consultation (b). Notes. This figure shows, from top to bottom, analogue patients’ mean systolic blood pressure, diastolic blood pressure and heart rate. Figure 3a, at the left, shows their cardiovascular activity at baseline and during the video-vignette introduction, stratified by introduction formats. Significant effect were shown on systolic blood pressure (p = 0.008) and diastolic blood pressure (p = 0.042), but not on heart rate (p = 0.896). Figure 3b, at the right, shows analogue patients’ mean cardiovascular activity at baseline and during the video-vignette consultation, stratified by introduction formats. Significant effect were shown on systolic blood pressure (p = 0.015) and diastolic blood pressure (p = 0.015), but not on heart rate (p = 0.314)
