Dear Helmut,

❝ Remark: even if the CV is not given, you can calculate it from the confidence limits and the sample size of a published study by means of a little bit of algebra ;-)

Can you please give some more details on the "little bit of algebra"? ;-)

How exactly can I calculate the CV on the basis of a published CI and sample size?

Thank you
Youri
