The number of systematic reviews being published each year is actually much larger than the already impressive number of 10,000 quoted. In 2017 over 20,000 were published; 20,661 are cited in the KSR Evidence database in early August 2018. KSR Evidence, includes all systematic reviews and meta-analyses published since 2015 and for many reviews provides a critical appraisal and a short, accessible bottom line. www.ksrevidence.com
I searched PubMed for the retraction notices. The 3 retracted articles published by Elsevier have no retraction notices in PubMed. Retraction notices for the 2 articles in the Journal of the American Society of Hypertension were published in vol. 9, issue 10, this issue is indexed in PubMed and articles citations are in PubMed but the two retraction notices are missing. "Publishers of journals in PubMed must submit citation and abstract" (PubMed FAQ for publishers), these two notices should normally have been submitted by the publisher. As for the article published in the European Journal of Pharmaceutical Sciences, no retraction notice was found, information about the article being retracted is available in the original article but, as no retraction notice seems to be available, there is no information about the retracted status in PubMed. As PubMed is often the source used by researchers doing a study on retractions of articles (e.g. PMID: 28683764, PMID 26797347, PMID: 24928194) it is important to find this information in the database. Publishers should always publish retraction notices for retracted articles and submit the citations to PubMed when the journal is indexed in this database.
In their editorial, Brodersen et al. present two types of overdiagnosis. Their two types appear to be identical to two types of overdiagnosis we identified in research published in 2016 (Rogers WA and Mintzker Y. Getting clearer on overdiagnosis. J Eval Clin Prac 2016;22: 580-587). In that paper, we provide a detailed account of maldetection overdiagnosis and misclassification overdiagnosis, together with an analysis of the relevance of these two different types.
This matter, including our request for a correction, is fully explained in our letter published in this journal: Response to Brodersen et al’s ’Overdiagnosis: what it is and what it isn’t' (http://ebm.bmj.com/content/early/2018/03/29/bmjebm-2018-110948).
