Table 4 Absence of preprocedural tension

	R	R2 adjusted	Regression coefficient B	SE	Beta	T value	P value
Satisfaction with medical counseling1	0.397	0.144	0.679	0.199	0.397	3.410	0.001
Composure after conventional counseling2	0.600	0.350	0.764	0.127	0.600	5.998	0.000

¹Absence of preprocedural tension depends mostly on patient satisfaction with conventional medical counseling (dependent variable: Preprocedural composure; independent variables: Understanding of possible risks and benefits after medical counseling, impression of the medical counseling being personally tailored to the patient, overall satisfaction with the counseling).

²Regression analysis of the absence of preprocedural tension after conventional counseling and the additional educational video (dependent variable) in relation to the comorbidities; independent variables: Preprocedural tension after conventional counseling, log European System for Cardiac Operative Risk Evaluation score (%) and Society of Thoracic Surgeons-score (%).

Table 5 Importance of conventional medical counseling for the absence of preprocedural tension

	R	R2 adjusted	Regression coefficient B	SE	Beta	T value	P value
Composure after conventional counseling	0.600	0.350	0.661	0.126	0.519	5.256	0.000
Understanding of benefits after conventional counseling	0.637	0.387	0.584	0.281	0.205	2.076	0.042
Understanding of benefits after watching the video	0.665	0.416	0.214	0.106	0.194	2.015	0.048

Composure after conventional counseling and the additional educational video. Dependent variable: Preprocedural composure; independent variable: Tension after conventional counseling, understanding of benefits after conventional counseling and understanding of benefits after the additional educational video.

	R	R2 adjusted	Regression coefficient B	SE	Beta	T value	P value
Composure after watching the educational video	0.568	0.312	0.319	0.067	0.492	4.754	0.000
Understanding of benefits of the procedure after watching the educational video	0.619	0.364	0.185	0.074	0.258	2.495	0.015

Regression analysis of patients’ desire to see the additional educational video as the dependent variable; independent variables: Understanding of risks and benefits of the procedure after conventional counseling, understanding of risks and benefits of the procedure after watching the additional educational video.
