Results with median Cohen’s kappa values for the Friedman stage, tongue position, and tonsil size

	Cohen´s kappa (1st and 3rd quartile)	Range	Agreement (Byrt)	Agreement (Altman)
Friedman stage (n = 91)	0.38 (0.24, 0.55)	−0.08 to 0.86	Slight	Fair
Tongue position (n = 91)	0.32 (0.21, 0.44)	−0.09 to 0.77	Slight	Fair
Tonsil size (n = 91)	0.62 (0.50, 0.63)	0.14 to 1.00	Good	Good

Data are shown as the median with first and third quartiles, range, and the corresponding agreement according to Byrt and Altman. Cohen’s kappa is between − 1 and 1, where 0 represents agreement that would be expected from random chance, and 1 represents perfect agreement. Negative values represent agreement that is less than would be expected from random chance alone
