In the originally published article, a sentence in the second last paragraph incorrectly used ‘thrombocytosis’ instead of ‘thrombosis’. This sentence has now been corrected to: ‘This results in biophysical and biomechanical changes in the RBC membrane that affect both the diffusion of oxygen and carbon dioxide and the deformability capability of RBCs in the capillary vessels, thereby favouring thrombosis.’
