Talk:Study: Children who socialise more, get cancer less

Notes regarding interpretation of 'odds' figures
The study Results summary section gives the chance of contracting leukaemia for each group compared against the children who had no significant social interaction outside the home.

For example: "odds ratios for increasing levels of activity were 0.73 (95% confidence inter val 0.62 to 0.87) for any social activity".

So this means children in category "any social activity" had a chance 0.73 times the chance that the "no social activity" children had, which could be given as 73%, or as 'around 3/4', or looking at it the other way, as given in The Australian's article "risk of ALL was 27per cent lower for babies who had any social activity" &mdash; the 27% being (100% - 73%), since they are saying how much the chance was decreased, rather than what proportion the decreased chance was of the maximum chance.
