Abstract
It is shown how the difference between the success rates in two treatment groups is related to the treatment-outcome correlation and the overall success rate. A new measure of effect size is proposed, which is easily calculated and readily interpretable in terms of the ratio of success rates in the treatment groups.Keywords
