C-TMD	>1 finger	186/2/0
C-TMD	<1finger	101/9/6	<0.001
IID	>3finger	175/5/1
IID	<3finger	112/6/5	0.023
ULBT	1 grade	120/2/1

Mallampati Test	<3 grade	124/9/0
Mallampati Test	>2 grade	163/2/6	0.064

The number of intubation attempts were compared using χ²or Fisher exact test for categorical variables
