Dear all, Despite searching the fullrefman file I have been unable to locate a function to calculate the relative risk and confidence intervals from a simple 2 by 2 contingency table. Can anyone tell me how this is done. Thanks in advance Malcolm ---------------------- MJ Price, Social Medicine epmjp at bristol.ac.uk
Malcolm, Install the 'epitools' package and use the 'epitab' function, and use method="riskratio" Tomas http://www.epitools.net http://www.medepi.net/aragon/
