Unpaired test was used for comparison of variables between two groups.
#Pearson chi-square and Fisher’s exact test were used for comparison of variables between the categorical data. *(1) Only larynx seen; (2) larynx and epiglottis posterior surface seen; (3) larynx and epiglottis tip of anterior surface seen, 50% visual obstruction of epiglottis to larynx; (4) epiglottis downfolded and its anterior surface seen, 50% visual obstruction of epiglottis to larynx; (5) epiglottis downfolded and larynx cannot be seen directly.
