Comparison of STAI-state score before and after the video-based MMI or written information in the two groups

Parameter	Video-based MMI group (n = 52)	Control group (n = 52)	P-value
STAI-S pre-informational	49.0 ±8.0	49.3 ±8.3	0.49
STAI-S post-informational	45.0 ±8.0	49.4 ±8.4	< 0.001
P-value’	< 0.001	0.15

Data are given as mean ± SD. STAI-S – State-Trait Anxiety Index-State, MMI – multi-media information. P-value – p-value derived from the comparison of the video and control groups. P-value’ – p-value derived from the comparison of the pre- and post-informational STAI-S scores.
