Correction: Cardiac mass and function decrease in bronchiolitis obliterans syndrome after lung transplantation: relationship to physical activity?

There is an error in Table 2. The value for unadjusted Right ventricle (RV) mass/BAS, gm/m2 in the BOS 0/0p is incorrect. The correct value is 30. Additionally, the value for the unadjusted ejection fraction, % BOS 0/0p is incorrect. The correct value is 64. Please see the corrected Table 2 here. The publisher apologizes for the error.
