Scope note: Estudios clínicos que implican uno o más tratamientos de prueba, al menos un tratamiento de control, medidas del resultado especificadas para evaluar la intervención estudiada y un método sin sesgo para asignar los pacientes al tratamiento de prueba. El tratamiento puede ser medicamentoso, con dispositivos o mediante procedimientos estudiados en relación con su eficacia diagnóstica, terapéutica o profiláctica. Las medidas de control incluyen placebos, fármacos activos, ausencia de tratamiento, formas y regímenes de dosificación, comparaciones históricas, etc. Cuando se utiliza la distribución aleatoria con empleo de técnicas matemáticas, como el empleo de una tabla de números aleatorios, para asignar los pacientes a tratamientos de prueba o de control, los estudios se denominan ENSAYOS CONTROLADOS ALEATORIZADOS COMO ASUNTO.

Scope note: Works about clinical trials involving one or more test treatments, at least one control treatment, specified outcome measures for evaluating the studied intervention, and a bias-free method for assigning patients to the test treatment. The treatment may be drugs, devices, or procedures studied for diagnostic, therapeutic, or prophylactic effectiveness. Control measures include placebos, active medicines, 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 trials are characterized as RANDOMIZED CONTROLLED TRIALS AS TOPIC.
