Mean pulmonary function test results by glycemic control in CFRD.

<p>CFRD subjects with HbA_1c > 6.5% had significantly reduced average scores of forced expiratory volume in one second (FEV₁, left panel) and forced expiratory flow in the 25–75% of the patient’s exhaled volume (FEF25–75%, right panel) compared to CFRD subjects with HbA_1c ≤ 6.5%. Diamonds are centered on each category’s mean and the vertical distance represents the 95% confidence interval.
