  1. Note: For comparison of intubation time and successful intubation time, a difference with P less than 0.05 was considered statistically significant, and indicated with “*”. The P value was calculated using the independent-sample Student t test or chi-square test. Data were expressed as mean ± standard deviation and number (percentage)
