Figure 3

Percentage of excessive, optimal, suboptimal and insufficient peak inspiratory flow rates measured against different resistances among patients <65 (Panel A, p < 0.01), 65–69 (Panel B, p < 0.01), 70–74 (Panel C, p < 0.01), 75–79 (Panel D, p < 0.01) and ≥80 years of age (Panel E, p < 0.01). * represents p < 0.05, ** represents p < 0.01.
