We are pleased to announce that the first article in the new  Methods and Statistics Tutorials series has been published in Cochrane Evidence Synthesis and Methods, Cochrane's new open access journal. 

Measuring dichotomous outcomes using risk ratios, odds ratios, and the risk difference: A tutorial gives an overview and worked examples of these different effect measures. The tutorial also includes a link to a micro learning module in which you can practice new skills and test your understanding. 

We welcome feedback on this tutorial, and also suggestions for future articles in this series. Please contact the series editors, Dr Kerry Dwan, Senior Lecturer in Evidence Synthesis at the Liverpool School of Tropical Medicine and Rachel Richardson, Methods Support Unit Manager at Cochrane at rrichardson@cochrane.org
