PFTs before and after HPT. (A) FVC, FEV1, and TLC for pulmonary function tests before and after HPT. (B) Percent predicted values (FVC%, FEV1%, TLC%) and FEV1/FVC for pulmonary function tests before and after HPT. FVC, forced vital capacity; FEV1, forced expiratory volume in the first second; TLC, total lung capacity; FVC%, percent predicted forced vital capacity; FEV1%, percent predicted forced expiratory volume in the first second; TLC%, percent predicted total lung capacity; CI, confidence interval; PFTs, pulmonary function tests; HPT, halo-pelvic traction.
