Competing demands for scarce healthcare resources have accentuated the requirement for routine clinical practice to be evidence-based. One of the benchmarks for evidence-based medicine is the appropriately conducted randomized controlled trial (RCT). Although epidemiological studies, whether casecontrol or cohort in design, have contributed enormously to the generation of hypotheses and permit the controlled evaluation of therapeutic interventions, they are susceptible to biases through selection, information ascertainment and confounding. While RCTs are also susceptible to such biases, the process of randomization and of blinded evaluation of outcomes permits the closest approximation in clinical research to the conduct of a hypothesis-testing laboratory experiment.
