What is comparator intervention?

The Intervention– the approach you’re evaluating. The Comparator– the approach you’re comparing the intervention to. The comparator could be a placebo or a control group, but often it’s a different type of medical treatment or the usual form of care.

What is a comparator RCT?

A comparator drug/intervention/treatment is an already approved and licensed drug/intervention/treatment that is currently being used on the market in clinical practice.

What is the comparator group?

Related Content. A group of companies that are selected according to size, sector, geographic spread, or other criteria, and used for the purpose of measuring relative performance or to benchmark a company against.

How do you choose comparators?

One criterion for selecting a comparator is the time its output takes to alter its state after a signal has been applied at its input. This propagation time must account for propagation delay through the component and rise/fall times in the output driver as well.

What is electronic comparator?

In electronics, a comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger. It has two analog input terminals and and one binary digital output .

What is the comparator in a research question?

The “C” in PICO represents the comparison intervention or control group. A central utility of research design is to test the efficacy of an intervention, exposure, test, or agent against a control group to see if it has any clinically meaningful effect above other treatments or nothing at all.

What is an active comparator trial?

The active comparator design refers to a study that compares the effect of ‘Drug A’, study drug of interest, to ‘Drug B’, another active drug used in clinical practice, instead of ‘no use’ (non-users). Non-users are subjects who have the disease of interest, but are not on treatment for the disease.

How does a comparator work?

Comparator Circuit Working and Applications. Generally, in electronics, the comparator is used to compare two voltages or currents which are given at the two inputs of the comparator. That means it takes two input voltages, then compares them and gives a differential output voltage either high or low-level signal.

What are the types of comparators?

Types of Comparators

• Mechanical Comparator.
• Mechanical-Optical Comparator.
• Reed Type Comparator.
• Electrical-Electronic Comparator.
• Pneumatic Comparator.

What is comparator and its application?

A comparator is an electronic component that compares two input voltages. Comparators are closely related to operational amplifiers, but a comparator is designed to operate with positive feedback and with its output saturated at one power rail or the other.

What is comparator and its types?

Comparators are classified into various kinds, such as electronic, electrical, mechanical, optical, sigma, digital and pneumatic comparators, these are used in various applications. The comparator is mainly designed without feedback for open loop configuration.

What is PEO research?

• PEO: Population/Problem/Patient, Exposure, Outcome. Example PICO/PIO Questions and Structures.

When to use a comparator in a clinical study?

The comparator drug to be used in the clinical study is considered an investigational new drug. Sponsors must comply with FDA’s IND regulations for both the comparator drug and the drug under investigation. An FDA-approved drug without modification is most often used as the comparator.

What is the medical definition of a comparator?

Medical Definition of comparator 1 : an apparatus used for determining concentration of dissolved substances (as hydrogen ions) in solution by color comparison with known standards

What’s the difference between a comparator and a control?

A comparator drug/intervention/treatment is an already approved and licensed drug/intervention/treatment that is currently being used on the market in clinical practice. Control can be a Placebo treatment or No treatment at all, or a treatment arm not receiving active drug treatment…
