Loss of follow-up is a problem in most cohort studies and often introduces bias. It is a situation in which a researcher loses contact with a subject, resulting in missing data. Too many subjects failing follow-up diminish the internal validity of the study.
<h3>What is follow-up loss in cohort studies? </h3>
- Follow-up loss introduces bias (observed deviation of relevant measures from what would have been observed without bias) if there is a difference in the likelihood of loss due to follow-up related to exposure status and outcome.
- In the clinical research trials industry, loss due to follow-up is defined as patients who were actively participating in a clinical research trial at some point but who lost themselves (due to errors in the computer tracking system or due to unavailability).
- In cohort studies: 1) Imaging outcome, is loss of follow-up. 2) These are essentially prospective studies, so confounding factors are not an issue. 3) These studies help examine multiple outcomes from a single, infrequent exposure. 4) These are usually faster and cheaper than case-control studies.
<h3>What are advantage and disadvantages of cohort studies?</h3>
- In general, the main advantage of cohort studies is the ability to study multiple exposures and multiple endpoints in a single cohort. This recording allows you to select index groups, so you can explore rare recordings.
- A major weakness of cohort studies is that this type of study design can be time consuming and expensive for results that are rare or evolve over long periods of time. It's a question of research.

The correct answer to this is the:
“Fidelity”
I believe Sally is violating fidelity simply just to make
her speeches more good sounding. Fidelity is described as being faithful or
being true to other people. By adding, subtracting or modifying some parts in
her speeches just to be more entertaining, she is not telling the real story at
all.

This semester, you have an assignment in which data collected from a previous assignment is included in the new project. Yes, we need to cite this information because it is academic practice to cite the previous work you have done.
In another instance, although you credited your sources and wrote a research paper, you forgot to record the page numbers for the in-text citations. You insert page numbers without double-checking them because the project is due in few hours. You cited someone, but you did so improperly, thus this is also a violation.
Following the right academic practice, while one submits their works, is essential as per the ethics.
