Table 2.

Testing the null hypothesis that spray particle penetrations past nasal valve for both sides of the nasal cavity are equal (Hypothesis #1).

Head Position	Airflow	Left Side (n=5)	Right side(n=5)	P-value
Upright	Present	62.6 ± 7.96	223.0 ± 8.97	<0.00001
Upright	Absent	15.2 ± 2.05	72.0 ± 6.44	0.00001
Head Back	Present	62.2 ± 7.79	220.0 ± 10.51	<0.00001
Head Back	Absent	29.0 ± 1.22	109.6 ± 10.01	0.00005
Mygind’s	Present	61.6 ± 7.77	219.2 ± 10.03	<0.00001
Mygind’s	Absent	105.6 ± 9.5	130.4 ± 9.99	0.00385

The values were presented as means ± standard deviation and were compared with the Student’s t-test. P-value<0.05 indicate statistical significance (all cases).
