) During a 56-week test, 3,731 patients participated in the double-blind trial. participants did not have type 2 diabetesmellitus. one group of participants received once-daily subcutaneous injections of liraglutide at a dose of 3.0 mg. The other participants received a placebo. Both groups received counseling on lifestyle modification. At the end of the 56 weeks, the bodyweight of each participant was determined. Which of the following best the question that was being investigated in the study? a. Can body mass index affect the onset of diabetes? b. Is liraglutide effective for weight loss? c. What effect does Liraglutide have on diabetes? d. How does lifestyle modification counseling affect body weight?

Answers

Once identified the controlled, the independent, and the dependent variables, we can say the question is B) Is liraglutide effective for weight loss?

To answer this question, what we need to do first is to identify the variables involved in the experiment.

What are the variables involved in an experiment?

Dependent variables

These are the variables whose response depends on any change in the independent variable.

Independent variables

These are all the variables in an experiment that provoke a response in another variable. They are modified in the experiment to analyze how another variable responds to it.

Controlled variable

Controlled variables are kept constant in an experiment. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.

In this experiment we can also identify two groups. The experimental group and the control one. Both groups are composed of individuals coming from the same population.

What is the control group?

The control group is used to identify any factors other than the modified variables of the treatment that might influence the results obtained in the study.

What is the experimental group?

This group gets the treatment to observe how the independent variable affects the individuals.

In the experiment,

Control group ⇒ receives placeboExperimental group ⇒ receives liraglutideindependent variable ⇒ liraglutidecontrolled variables ⇒ lifestyle modification, participants did not have type 2 diabetes mellitus.dependent variable ⇒ bodyweight of each participant

According to the identification of the variables, the question that was being investigated in the study is option B) Is liraglutide effective for weight loss?
