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.

Answer: Informed consent from participants
Explanation:
Informed consent is defined as the acknowledgment and permission that is provided to the participant of any research experiment for letting them know about possible consequences of it. Participants get to know about risk and advantages that is involved in study .
According to the question,if researcher find individuals for interview, he/she should ask their permission and inform about subject,possible result and risk of the research to gain informed consent from all the participants.
The correct answer to this open question is the following.
Although there are no options attached, we can say that step in the IDEAL model that the beginners are neglecting is the Diagnosing step.
While beginners tend to jump right into proposing solutions, experts tend to spend time thinking about the underlying causes of the problem and interpreting it from different perspectives. This is because experts know that they need to spend some time trying to find the correct causes that originated a problem. This allows them to understand the origin of the problem, not only the symptoms. When experts understand different perspectives and view the issue through different angles, they will have more chances to make a better decision and act correspondingly.
After the Diagnosing phase of the model, it comes Establishing, Acting, and Learning.
This is known as cultural relativism.
Cultural relativism refers to the fact that customs and beliefs of foreign nations should be considered objectively, within that particular culture, rather than your own culture. So, anthropologists who are studying female circumcision should be objective when it comes to this controversial topic because even though that may not be acceptable in their own culture, it is acceptable in some other cultures.
The League of Nations, was the first worldwide intergovernmental organisation whose goal was to maintain world peace. Hope this helps.
