In other cases, the adverse effects emerged only after the drugs had gone to market and were being used by large numbers of patients.

That initial sense of relief disappeared in the days that followed as the side effects emerged.

This gene-environment interaction was not apparent at age 10 months, suggesting that the effect emerges over the course of early development.

The authors argued that the effect emerges most clearly from studies within families.

The effects of these changes have been emerging gradually.

Children and the elderly are said to be the most vulnerable, but the effects of unusual stress can emerge among others.

So, other side effects may emerge over time.

But if the drug is used by vast numbers of people for extended periods of time, adverse effects may emerge.

The effects of decisions and actions emerge only over decades.

Another problem is the concept of post-project assessment, when certain things, including environmental impact analysis, are not mentioned and some side effects emerge later.
