Changes in pulmonary diagnoses at baseline, 6 months and 12 months. For 44 participants with a normal baseline pattern, 35 (80%) remained normal at 12 months, while 6 (14%) developed incident obstruction, 1 (2%) developed restriction, and 2 (5%) developed a mixed pattern. For 10 participants with obstruction at baseline, 7 (70%) had normalized at 12 months, while 3 (30%) had persistent obstruction. For 22 participants with restriction at baseline, 12 (55%) had normalized at 12 months, while 8 (36%) had persistent restriction, 1 (5%) had developed obstruction in addition to restriction (i.e., a mixed pattern), and 1 (5%) had obstruction alone. For 5 participants who had a mixed pattern both at baseline, 2 (40%) had normalized at 12 months, 2 (40%) had persistent restriction, and 1 (20%) had a persistent mixed pattern
