 Figures on SIDS-risk for the interaction between breastfeeding,
 smoking and bed-sharing are not published in the CESDI report,
 nor in any of the articles arising from this study that I know
 of. The interactions between smoking and SIDS, and bed-sharing
 and smoking and SIDS were addressed. Breastfeeding was found to
 be neither protective, nor a risk factor, for SIDS in this study.
 I asked the project statistician several years ago how
 breastfeeding fitted into the smoking and bed-sharing picture.
 Despite the CESDI study examining 325 cases of SIDS and 1300
 controls over a 3 year period, he said the numbers were so small
 (SIDS cases who were breastfed and who had a parent who smoked
 was a small subset of the cases, and then dividing these into
 bed-sharers and non-bed-sharers produced two even smaller
 subsets) that they were too small to form the basis of a risk
 calculation. Which is why, in the UK at least, I don't think we
 have the data to give a clear answer...
