Abstract

This Cochrane Review was withdrawn from publication on 23 October 2013 by the Co‐ordinating Editor of the Cochrane Airways Group with the agreement of the authors. The Cochrane Review has been replaced by two new Cochrane Reviews with updated methods:

  1. Milan SJ, Hart A, Wilkinson M. Vitamin C for asthma and exercise‐induced bronchoconstriction. Cochrane Database of Systematic Reviews 2013, Issue 10. Art. No.: CD010391. DOI: 10.1002/14651858.CD010391.pub2.

  2. Wilkinson M, Hart A, Milan SJ, Sugumar K. Vitamins C and E for asthma and exercise‐induced bronchoconstriction. Cochrane Database of Systematic Reviews 2014, Issue 6. Art. No.: CD010749. DOI: 10.1002/14651858.CD010749.pub2.

A previous version of this review, published on 21 January 2009, received comments from H. Hemilä (Department of Public Health, University of Helsinki, Helsinki, Finland). In response to this feedback the review was updated and published on 20 June 2012 PMID: 19160185], as follows: (1) removed three instances of reporting of baseline lung function values; and (2) deleted statistical data from a trial that only reported data on participants who benefited from treatment.

The parts of the review affected by these changes are the section on Effects of interventions, the first paragraph of the Discussion section, and Data and Analyses Table 1: Oral vitamin C vs placebo (single‐dose studies).

The uncorrected version of the review (published 21 January 2009) is no longer available in the Cochrane Database of Systematic Reviews, but can be accessed via PubMed Central: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6176494/.

This statement was revised on 29 October 2018 to clarify the reason for withdrawing the review, provide information about previous amendments to the review, and include a link to the 2009 publication in PubMed Central.

The editorial group responsible for this previously published document have withdrawn it from publication.
