## Tools (as reported by the server, not verified)

- `search\_studies`: Find molecular hydrogen studies by keywords and/or filters. Returns compact study records \(design, subject, sample size, delivery method, outcome, key finding, url\). Sorted by relevance when a query is given, otherwise by strength of evidence.
- `get\_study`: Full record for one study: citation, design, population, H2 protocol \(delivery, concentration, dosage\), outcome, our plain-language summary and key finding, limitations, quality score with red flags, conditions/mechanisms, and links. Accepts an id, slug, DOI or study URL.
- `get\_condition\_evidence`: Evidence profile for a health condition hub: how many studies, human vs animal vs in-vitro, number of human RCTs and participants, outcome mix, delivery methods, publication years, data coverage, and the strongest studies.
- `compare\_evidence`: Side-by-side evidence profiles for 2–4 groups of studies, e.g. inhalation vs drinking water for one condition, or two conditions. Each group is a set of filters merged over the optional shared filters.
- `aggregate\_studies`: Count matching studies grouped by year, subject, design, delivery\_method, outcome, country, condition or species — for trends and 'how many' questions. Unknown values are counted separately.
- `find\_related\_studies`: Studies a given study cites, studies that cite it, and the most similar studies by shared health conditions.
- `list\_conditions`: Every health condition hub with its study count, evidence grade \(where reviewed\) and page URL. Use the slug as the \`condition\` filter.
- `get\_database\_stats`: Size and makeup of the database: total studies, breakdown by subject and design, year range, and field coverage.
