Description of the BLS intervention.
Description of the educational intervention in the cluster randomised controlled trial, comparing learning outcome after training in basic life support (BLS) with training in basic life support including a preparatory web-based education on cardiovascular disease (BLS+WEB). Abbreviations: BLS, basic life support; BLS+WEB, basic life support plus a web-based education; SCA, sudden cardiac arrest; CPR, cardiopulmonary resuscitation; AED, automated external defibrillation; CVD, cardiovascular disease; AMI, acute myocardial infarction.

Flow chart according to CONSORT (www.consort-statement.org), to compare the effectiveness of basic life support (BLS) education with preparatory web-based education in cardiovascular disease (CVD) in addition to BLS training (BLS+WEB). The participants were randomised, educated in BLS and assessed for their total score in practical skills of BLS. The post-test was performed directly after training and the retention test was performed six months after training. The main intervention was BLS education compared with BLS+WEB education. Additional training comprised self-learning training (SLT), instructor-led training (ILT), instructions from a mobile application (A), instructions from a video film (F), three reflective questions (R) and a device for feedback on compression depth (CF).
