Fig. 2: Significantly altered nasal airflow in PD across time during wake.
From: Discriminating Parkinson’s disease patients from healthy controls using nasal respiratory airflow
a–c Each panel contains line plots of a nasal airflow parameter during wake from starting point of the recording, for PD patients (red) and healthy controls (blue) followed by a box plot for that parameter during wake. For the time-line, solid line is the mean, and shade represents SEM. For the box-plots, Central lines indicate median, Edges of the box indicate 75th and 25th percentiles. Whiskers reflect 1.5 times the interquartile range. a Duty Cycle inhale, P = 0.005. b Breathing rate variation coefficient, P = 0.0006. c Duty cycle inhale pause, P = 0.01. n(control) = 33, n(PD) = 28. The plot is restricted to the duration of the one patient that provided least wake data (390 min). Overall wake recordings ranged from 390 to 1135 min (mean = 868.5 ± 147.7). d The combined score in PD and controls, P = 4.3 × 10−5. e The relation of the combined score to age, P = NS. f The relation of the combined score to disease severity, P = NS. g The relation of the combined score to medication status, P = NS.
