Unfortunately, the above paper has cited an incorrect reference relating to the effects of nifedipine and not β₂-agonists in asthma patients, as stated in the Discussion. Reference 26 should be as follows.

Ballester E, Reyes A, Roca J, Guitart R, Wagner PD, Rodriguez-Roisin R. Ventilation-perfusion mismatching in acute severe asthma: effects of salbutamol and 100% oxygen. Thorax 1989; 44: 258–267.
