aThe P value was obtained from the general linear regression model adjusted for age, sex, educational level, exercise habits, whether CPR training was being received for the first time, and BLS pretest knowledge score.
bBLS: basic life support.
cItalic formatting indicates that there is a statistically significant difference in the P value.
dCPR: cardiopulmonary resuscitation.
eP values obtained from the chi-square test. High-quality CPR was denoted by an average compression depth between 5 and 6 cm, an average compression rate of 100-120 beats per minute, and 80% chest recoil.
