A statement of no difference in experimental treatments indicates that there is no statistically significant effect observed between the groups being compared in an experiment. This means that the treatments did not result in a measurable difference in the outcome being studied. It suggests that any observed variations between groups could have occurred by chance and are not due to the treatments themselves.
A statement of no difference in experimental treatments indicates that there was no significant effect observed between the groups being compared. It suggests that the results obtained from the treatments were similar or not statistically different from each other. This is often reported after statistical analysis has been performed to determine if there is a significant difference between groups.
When setting up an experimental procedure one prepares a control treatment as well as one or more experimental treatments. At the end of the experiment, if there is no difference between the experimental and control groups the experiment is typically said to be not conclusive. With a typical set-up, this result generally fails to lead to a rejection of the null hypothesis.

Compassionate use and expanded access both allow patients to access experimental treatments, but there are key differences. Compassionate use is when a single patient is given access to an experimental treatment outside of a clinical trial due to a life-threatening condition. Expanded access, on the other hand, is when a group of patients with a similar condition are given access to an experimental treatment.
An analysis of variance (ANOVA) test is commonly used to analyze data from experimental treatments to determine if there are statistically significant differences between groups. This test compares the means of multiple groups to assess whether any differences observed are due to the treatments or simply random variation.
