Prevention and Intervention

Preprint

A manuscript shared before formal peer review and publication. Check whether a later published version is available.

Dataset

A collection of data or examples for others to inspect or reuse. It can appear in Library search and topic mapping, but RSRC does not use dataset records as evidence in Research Insights.

Dissertation or thesis

Research submitted for an academic degree. This describes its format, not its reliability.

Journal article

An article published in a journal. This label alone does not establish peer review, study quality, or how well the findings apply elsewhere.

Definitions draw on DataCite resource types; Cochrane review methods; NLM: association and causation. RSRC’s dataset and classification rules are explained in our methodology.

Qualitative research

Examines experiences, meanings, or processes, often through interviews or observations. It can explain how something happens without estimating how common it is.

Quantitative research

Uses numerical measurements to describe patterns or test relationships. A relationship between two measurements does not by itself show that one causes the other.

Systematic review

Uses a planned, documented method to find and assess research addressing a question. Its conclusions still depend on the included studies and what the search covered.

Meta-analysis

Statistically combines results from multiple studies. Combining studies does not remove weaknesses in their design or make unlike populations interchangeable.

Not classified

This record has no recognized label in this filter. It does not mean the publication used no method, or that no research exists.

Groups studied

People or groups described in the research, where recorded. One publication can have several labels. Missing labels are a catalog limitation, not evidence that a group has never been studied.
