This chart has an inaccurate formula for relative risk reduction. It should read "(CER-EER)/CER"http://gim.unmc.edu/dxtests/effect1.htm

Corrected :)— Precedingunsigned comment added byNeo1738 (talk • :contribs)19:54, 3 March 2011 (UTC)[reply]

In the referenced text the correct formula would be the absolute number of (CER-EER) (see a bit further down in the section about ARR), and mathematically that´s equal to the absolute number of (EER-CER); e.g. ABS(1-0.5)=ABS(0.5-1).

By using the absolute numer you loose the information (contained in the sign of the result) if it is a risk reduction or increase, which will have to be provided in the text.

I have restored the semantically and mathematically correct formula in the template.T.pienn (talk)13:38, 5 April 2014 (UTC)[reply]

Y Formulas for reduction, increase and change were separated and are now unambiguous, as well as match the references.Psarka (talk)21:30, 8 September 2018 (UTC)[reply]
