No, because I did not want to use the original numbers in the 
request. So as the snippet below indicates I changed the numbers. If 
I apply Wolfgang's suggestion (which I had already thought of but 
discarded) I get about 13 for the real example where the authors quote about 5.

My question still remains though as to how I can get a confidence 
interval for the risk ratio without adding a constant to each cell.
