Qualifier English: Controlled Clinical Trial
Qualifier Spanish: Ensayo Clínico Controlado
Descriptor ensayo clínico controlado
Scope note: Trabajo que describe los resultados de un estudio clínico consistente en uno o más tratamientos a prueba, al menos un tratamiento de control, medidas de resultado especificadas para evaluar la intervención estudiada y un método, sin sesgos, para asignar a los pacientes al tratamiento de prueba. El tratamiento puede estar basado en fármacos, dispositivos o procedimientos estudiados para valorar la eficacia diagnóstica, terapéutica o profiláctica. Las medidas de control incluyen placebos, medicamentos activos, ausencia de tratamiento, formas y regímenes de dosificación, comparación histórica, etc. Cuando se recurre a la aleatorización con técnicas matemáticas, como el uso de tablas de números aleatorios para la asignación de los pacientes a las pruebas o tratamientos de control, hablaríamos de ENSAYO CLÍNICO CONTROLADO ALEATORIZADO.

The treatment may be drugs, devices, or procedures studied for diagnostic, therapeutic, or prophylactic effectiveness. Control measures include placebos, active medicine, no-treatment, dosage forms and regimens, historical comparisons, etc. When randomization using mathematical techniques, such as the use of a random numbers table, is employed to assign patients to test or control treatments, the trial is characterized as a RANDOMIZED CONTROLLED TRIAL.
