| Summary of Findings | From 126 included systematic reviews of asthma treatment, 23.5% of reviews were of low methodological quality and 61% were of critically low quality. Cochrane reviews and reviews with a European corresponding author were significantly more likely to be high quality than non-Cochrane systematic reviews or reviews with a corresponding author from America, Asia or Oceania.. |
