🟢search_studies(query, condition, subject, design, delivery_method, ...)

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.
