Thanks again for your input.

Nick, in your last post, are you suggesting an alternative way of presenting things as I'm not sure I follow what you mean by:

' I'd much prefer to work at a graphical display of odds
ratios and confidence limits with variable labels as horizontal text'

If there is another better (in your opinion) way of presenting what I have, then I'd be happy to know.

Best wishes

Tim

Although it's a fair way from the question, I will add that if I had
your problem I'd much prefer to work at a graphical display of odds
ratios and confidence limits with variable labels as horizontal text.
