Discriminating Parkinson's disease patients from healthy controls using nasal respiratory airflow.

If we indeed repeat the above analyses concentrating on the initial 30 min alone, we again observe highly significant differences in Duty Cycle Inhale (mean PD = 0.3 ± 0.07 (ratio), Control = 0.23 ± 0.06 (ratio), Wilcoxon rank-sum test, z = 4.2, effect size Cliff’s δ = 0.63, 95% CI = 0.36 – 0.8, P = 6.9 × 10 −5 ), breathing rate variation coefficient (mean PD = 0.26 ± 0.11 (ratio), Control = 0.38 ± 0.13 (ratio), z = −4.3, effect size Cliff’s δ = −0.64, 95% CI = −0.81 – (−0.37), P = 5.3 × 10 −5 ), and duty cycle inhale pause (mean PD = 0.2 ± 0.1 (ratio), Control = 0.29 ± 0.1 (ratio), z = −3.06, effect size Cliff’s δ = −0.45, 95% CI = −0.68 – (−0.17), P = 0.006) (Fig. 3a–d ).
