Development reasons. The idea was born in the Institute for Med. Statistics and Epi­demio­logy of the TU Munich. The objective was to facilitate the evaluation of PubMed search results, e.g. “Who has published about what?” or “Which therapies exist?”

A long article list from PubMed is hard to analyse, field relations are invisible. But this list is more informative than you may think!

First steps. The Result Help explains a Meva report. The Form Help assists with advanced analysis features. Finally, consult Meva.

Additional information. The Field Help details all field types available in PubMed and Meva. FAQ, Toolbox, Glossary and History clarify further aspects of usage, important terms and development of Meva.
