The study was not set up to look at any differences between the two. The numbers were very small and there was uncertainty over their significance, said the researchers. It is an important point but we cant at the moment say anything about that, he said.

Sheikh cautioned at a media briefing that the results are preliminary data, yet to be peer-reviewed by independent scientists, but added: I am very encouraged.
