Looking at some local work, by Willie Hamilton and others in Exeter on
colorectal cancer referral accuracy.
How does one combine a set of odds ratios?
eg
rectal bleeding 16
Loss of weight 2.9
Hb below 10g/dl 16
Doing an ECMAscript or whatever calculator is easy enough, but understanding
the calculation is rather harder.
A pointer to a primer would be appreciated if it is an FAQ
