Text: Overall, an abdominal binder resulted in a statistically significant improvement in forced vital capacity (weighted mean difference. 34 L [95 % confidence interval (CI). 10 -. 58], P =. 005), forced expiratory volume in 1 second (. 25 L [95 % CI -. 01 to. 51], P =. 05), peak expiratory flow (. 81 L/s [95 % CI. 13 -1. 48], P =. 02), maximal inspiratory pressure (7. 40 cm H (2) O [95 % CI 1. 64-13. 14], P =. 01), and maximum sustained vowel time (3. 75 s [95 % CI. 90 -6. 60], P =. 01).
