Table 3.

Aggregate mean and 95% CI ranges for all variables with corresponding volume and age effects.

Parameter	Aggregate Mean Range^a (sec)	Aggregate 95% CI Width^b (sec)	Volume Effect?	Age Effect?
UES opening duration	0.46	0.52	Yes	Yes
LCD	0.76	1.04	Yes	Maybe
HMD	0.60	0.96	Maybe	No
STD	0.76	1.04	No	Yes
PTT	0.84	1.07	No	Maybe
LC-to-UES-opening	0.18	0.36	No	Maybe

Calculated by subtracting the minimum reported mean value from the maximum reported mean value across the studies reviewed.

Calculated by subtracting the minimum value for the 95% CI lower boundary from the maximum value for the 95% CI upped boundary across the studies reviewed.
