Table A2 –

Pearson correlation coefficients (r), 95% confidence intervals, and P values between subjective nasal patency scores (NOSE and VAS) and regional airflow (inferior, middle, superior) measured either in the narrow side or in the non-narrow side at sections D=0.3, D=0.5, and D=0.7. N.S. = Not significant at level p<0.05.
