Intraclass Correlation Coefficients for Intra and Inter-reliability for thymic parameters measured on ultrasound scan. 3VV (3 vessel-view), 3VT (3 vessel-trachea view), APD (anterior-posterior diameter), ITD (intrathoracic diameter), TTR (thymic: thoracic ratio), TD (transverse diameter), 3VE (3-vessel-edge). Acceptable ICC values (>0.75 [29]) that are clinically significant (P< = 0.05) are in bold.
