ICH E9

ICH E9 is a set of guidelines developed by an international organization to improve the design and analysis of clinical trials, which test new medicines or treatments. It helps ensure that these studies are conducted consistently, accurately, and ethically, so that the results are reliable and can be trusted for making healthcare decisions. Essentially, it provides a framework for planning and analyzing trials to minimize errors and bias, ensuring that the findings truly reflect the effects of the treatment being tested.
