Safer fertility drug for women leads to same live birth rate

Issue: BCMJ, vol. 53, No. 6, July August 2011, Page 297 News

With new information available, authors of a Cochrane Systematic Review have revised their conclusions about the relative effectiveness of two treatments used to help women be­come pregnant. They now conclude that giving women gonadotrophin-releasing hormone (GnRH) antagonists leads to similar live-birth rates compared with GnRH agonists. Previously they had concluded that women who used antagonists tended to have lower birth rates than those using agonists. 

The systematic review also show­ed that GnRH antagonists can halve the risk of over-stimulating the ovaries compared with GnRH agonists, as well as halving the number of women who have to pull out of a cycle of therapy. 

In 2006, when the researchers reach­­ed their earlier conclusion, they were only able to draw data from 27 trials. Since then more research has been published, allowing them to consider the findings of 45 randomised controlled studies that involved a total of 7511 women.

Above is the information needed to cite this article in your paper or presentation. The International Committee of Medical Journal Editors (ICMJE) recommends the following citation style, which is the now nearly universally accepted citation style for scientific papers:
Halpern SD, Ubel PA, Caplan AL, Marion DW, Palmer AM, Schiding JK, et al. Solid-organ transplantation in HIV-infected patients. N Engl J Med. 2002;347:284-7.

About the ICMJE and citation styles

The ICMJE is small group of editors of general medical journals who first met informally in Vancouver, British Columbia, in 1978 to establish guidelines for the format of manuscripts submitted to their journals. The group became known as the Vancouver Group. Its requirements for manuscripts, including formats for bibliographic references developed by the U.S. National Library of Medicine (NLM), were first published in 1979. The Vancouver Group expanded and evolved into the International Committee of Medical Journal Editors (ICMJE), which meets annually. The ICMJE created the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals to help authors and editors create and distribute accurate, clear, easily accessible reports of biomedical studies.

An alternate version of ICMJE style is to additionally list the month an issue number, but since most journals use continuous pagination, the shorter form provides sufficient information to locate the reference. The NLM now lists all authors.

BCMJ standard citation style is a slight modification of the ICMJE/NLM style, as follows:

  • Only the first three authors are listed, followed by "et al."
  • There is no period after the journal name.
  • Page numbers are not abbreviated.
