Table 2.

Table showing Pearson Correlation Coefficients (r and r2) of 2D ultrasound measurements compared to Thymus Volume (TV). 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). Clinically significant P values are in bold.
