Quizplus · Accepted Answer

Group B is the control group, which is used to establish a baseline for comparison with the active treatment group (Group A). Group B receives an empty capsule, which is an analog of the active medication, to ensure that any observed effects in Group A are due to the medication and not any placebo effect.
