Park, Cha, Ko, Hwang, Hong, and Lee: Corrigendum to “Exposure to Dichlorodiphenyltrichloroethane and the Risk of Breast Cancer: A Systematic Review and Meta-analysis [Volume 5, Issue 2, April 2014, Pages 77–84]”
The authors regret that the Cohn et al (2007) article was incorrectly categorized into hospital case-control in this study. It is now reproduced correctly at the text and Tables 1 and 2 correspondingly. The authors also corrected the term of DDE for their consistency as below.
  • The numbers of study in the Methods of the Abstract and the second paragraph in the Results section should be corrected as follows.

    • 16 hospital-based case-control studies → 15 hospital-based case-control studies

    • 10 nested case-control studies → 11 nested case-control (prospective) studies

  • The design of Cohn (2007)'s study in Table 1 should be corrected to Nested CC.

  • The results related to study design in Table 2 should be changed as follows.
