Results of performance data for the different study groups in the three evaluations. Data in x = n and percentage of respective group size or in absolute numbers ± standard deviation.
Time to start CPR in seconds. Compression without faults: adequate compression depth and correct chest well decompression. Significant differences between groups are indicated bold.
Significant differences between time-points:
* baseline = > 1 week: p < 0.0001; $ baseline = > 1 week: p = 0.0003; † baseline = > 1 week: p = 0.0089;
‡ baseline = > 1 week: p = 0.006; ¥ baseline = > 1 week: p = 0.0072.
# baseline = > 6 months: p < 0.0001; £1 baseline = > 6 months: p < 0.0014; £2 baseline = > 6 months: p < 0.0496.
