MOESM2 of Diaphragmatic ultrasound findings correlate with dyspnea, exercise tolerance, health-related quality of life and lung function in patients with fibrotic interstitial lung disease

Additional file 2: Line graph depicting diaphragmatic mobility at quiet (QB) and deep breathing (DB) and diaphragmatic thickness at functional (FRC) and total lung capacity (TLC) of all subjects (healthy controls and FILD cases). Figure S1. Comparison of diaphragmatic mobility between healthy controls and FILD cases. Diaphragmatic mobility during QB was similar between groups (p = 0.95), but during DB, diaphragmatic mobility was lower in the FILD cases when compared to healthy controls (p <  0.01). At FRC, the diaphragm of FILD cases was significantly thicker (p 0.01) than the healthy controls. But, at TLC, the diaphragm of FILD cases was significantly thinner than the healthy controls (p < 0.01).
