Vitamin C supplementation for asthma [Feedback] version 2012

Abstract

Feedback to the following Cochrane review: Kaur B, Rowe BH, Arnold E: Vitamin C supplementation for asthma. Cochrane Database Syst Rev. 2009 Jan 21;(1):CD000993. http://www.ncbi.nlm.nih.gov/pubmed/19160185. This is the version available at Cochrane library that has Figures 1.1, 1.3, and 1.5 removed after publication and the remaining figures were renumbered so that Hemilä's Feedback text is inconsistent with the revised figure numbers. This version has doi address: https://doi.org/10.1002/14651858.CD000993.pub3/full. The original (2009) version with all the original figures 1.1 to 1.6 is available at PubMedCentral: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6176495, but that does not have Hemilä's Feedback text. The 2010 version of the Cochrane review has the Feedback text and the original Analysis figures 1.1 to 1.6 so that the Feedback text is consistent with the Figures and that is available at the University of Helsinki Digital Repository at https://helda.helsinki.fi/handle/10138/225865.
