OVI: Obstructive Ventilatory Impairment. RVI: Restrictive Ventilatory Impairment. For the remaining abbreviations, see table 3. Data were number (%). * p-value < 0.05: 2 sided Chi-square test: comparison between the 2 groups. Notes: 1. ACPA - group: among the 3 subjects with an OVI, 1 had lung-hyperinflation, and among the 3 subjects with lung-hyperinflation, 1 had an OVI. 2. ACPA + group: among the 10 subjects with an OVI, 9 had lung-hyperinflation, and among the 11 subjects with lung-hyperinflation, 9 had an OVI
