Review[Evolution of epidemiological methods in clinical research in Spain (1975-1994)].
Previous studies have shown a sparing utilization of analytical and experimental designs in Spanish clinical research journals. The study aims are to compare among countries, the use of epidemiologic method in articles published in scientific journals, and to determine the extent to which this research has direct funding. ⋯ In Spanish clinical journals the use of epidemiological methods with control group is limited and direct financial support unusual. Wherefore these studies have a limited applicability.
