# PubMed Database

Use this skill when a task needs biomedical literature from PubMed rather than
general web search.

## When to Use

- Searching MEDLINE or life-sciences literature.
- Building PubMed queries with MeSH terms, field tags, dates, or article types.
- Looking up PMIDs, abstracts, publication metadata, or related citations.
- Running systematic-review search passes that need repeatable search strings.
- Using NCBI E-utilities directly from Python, shell, or another HTTP client.

## Query Construction

Start with the research question, split it into concepts, then combine concepts
with Boolean operators.

```text
concept_1 AND concept_2 AND filter
synonym_a OR synonym_b
NOT exclusion_term
```

Useful PubMed field tags:

- `[ti]`: title
- `[ab]`: abstract
- `[tiab]`: title or abstract
- `[au]`: author
- `[ta]`: journal title abbreviation
- `[mh]`: MeSH term
- `[majr]`: major MeSH topic
- `[pt]`: publication type
- `[dp]`: date of publication
- `[la]`: language

Examples:

```text
diabetes mellitus[mh] AND treatment[tiab] AND systematic review[pt] AND 2023:2026[dp]
(metformin[nm] OR insulin[nm]) AND diabetes mellitus, type 2[mh] AND randomized controlled trial[pt]
