Early detection of treatment effects can make a big difference in a child's life.

The programs show good maintenance and generalization of treatment effects when the child was returned to the natural classroom.

However, the individual estimates of treatment effect will vary by chance; some variation is expected.

They can also be used to monitor the treatment effect of drugs.

Some of the treatment side effects can be avoided.

The latter can have an important impact on the average size of a treatment effect.

This analysis would be expected to provide the best chance of demonstrating a treatment effect, but no such response was found.

Trust is very important between patients and the doctors to help patients get better treatment effect.

This leads to a dilution of treatment effect, as will be explained.

The "treatment effect" is the difference between these two potential outcomes.
