Automating the study of clinical hypotheses on a time-oriented data base: the RX Project
Robert L. Blum · 1979
The existence of large chronic disease data bases offers the possibility of studying hypotheses of major medical importance. An objective of the RX Project is to assist a clinical researcher with the tasks of experimental design and statistical analysis. A major component of RX is a knowledge base of medicine and statistics, organized as a frame-based, taxonomic tree. RX determines confounding variables, study design, and analytic techniques. It then gathers data, analyzes it, and interprets results. The American Rheumatism Association Medical Information System is used.
