Clinical Burden of Chronic Obstructive Pulmonary Disease in Patients with Suboptimal Peak Inspiratory Flow

<div>Mean (a) mMRC score and (b) BDI in participants with oPIF and sPIF against the medium-low resistance DPIs. BDI = baseline dyspnea index; CI = confidence interval; DPI = dry powder inhaler; mMRC = modified Medical Research Council; oPIF = optimal PIF; PIF = peak inspiratory flow; sPIF = suboptimal PIF.</div>
