[Information on the use of laboratory animals indicated in scientific articles]

A sample of 15 Costa Rican scientific papers published since 1985 reported only 49% of the necessary information about laboratory animals and experimental conditions, slightly better than in the rest of Latin America (47%, sample = 15 papers) but lower than in the USA and Europe (60%, sample = 15). Adequate information on laboratory animals use for biomedical research is important to standardize their use.
