Table 2. Participants’ knowledge and awareness on BLS and AED-use stratified by gender and age-groups.
Discrete data are presented as counts and percentages and were compared using Chi-Square test. Logistic regression model for the association age, gender and first-aid education on the awareness and knowledge concerning BLS and AED use. Data are presented as odds ratio (OR) and the respective 95% confidence interval (CI).
