Why is a control group important?

This group serves as a benchmark, allowing researchers to compare the experimental group to the control group to see what sort of impact changes to the independent variable produced. 1 .
What is adherence to intervention protocol?
Adherence to intervention protocols refers to the degree to which the behaviour of trial participants corresponds to the intervention assigned to them. 154 Distinct but related concepts include trial retention ( Item 18b) and adherence to the follow-up protocol of procedures and assessments ( Item 13 ).
What are eligibility criteria for potential trial participants?
Eligibility criteria for potential trial participants define the study population. They can relate to demographic information; type or severity of the health condition; comorbidities; previous or current treatment; diagnostic procedures; pregnancy; or other relevant considerations. 125 In trials of operator-dependent interventions such as surgery and psychotherapy, it is usually important to promote consistency of intervention delivery by also defining the eligibility criteria for care providers and centres where the intervention will be administered. 126

Why do trials need to be modified?
For a given trial participant, the assigned study intervention may need to be modified or discontinued by trial investigators for various reasons, including harms, improved health status, lack of efficacy, and withdrawal of participant consent. Comparability across study groups can be improved, and subjectivity in care decisions reduced, by defining standard criteria for intervention modifications and discontinuations in the protocol. Regardless of any decision to modify or discontinue their assigned intervention, study participants should be retained in the trial whenever possible to enable follow-up data collection and prevent missing data ( Item 18b). 152
What are the outcomes of a trial?
The trial outcomes are fundamental to study design and interpretation of results. For a given intervention, an outcome can generally reflect efficacy (beneficial effect) or harm (adverse effect). The outcomes of main interest are designated as primary outcomes, which usually appear in the objectives ( Item 7) and sample size calculation ( Item 14 ). The remaining outcomes constitute secondary or other outcomes.
What is a clear timeline?

These factors can also affect the decision of potential investigators and participants to join the trial ( Item 15 ). 91
What is the purpose of randomization?

By randomization, research participants have an equal chance of being selected into any treatment group of the study, generating comparable intervention groups, thereby distributing the confounders. A trial can be “open labeled” or “blinded.”.
