Glossary

The NICE glossary provides brief definitions and explanations of terms and jargon used on our site. The terms describe how we work and how our guidance is produced.

Our glossary excludes specific clinical and medical terms although we intend to include these in the longer term. If you cannot find the term you are looking for, please email us so that we can consider adding it to the glossary. New terms are added regularly.

The glossary is not used for indexing the site or for navigation - for information on this, please see the NICE taxonomy.

Some definitions and examples are based on those in the ‘HTAi consumer and patient glossary’, with thanks to Health Technology Assessment International.

 

Literature review

Collecting, reading and assessing the quality of published (and unpublished) articles on a given topic. Also called a narrative review.

Longitudinal study

A study of the same group of people at different times. This contrasts with a cross-sectional study, which observes a group of people at one point in time.

Low income household

A low income household has only 60% of the average household disposable income. This is one of a set of indicators in the Opportunity For All report used to monitor the Government's strategy to tackle poverty and social exclusion. It has also been agreed by the Statistical Programme Committee of the European Union as the basis for making international comparisons of numbers of people on low incomes.
