The answer to this question is false.
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.

When deciding for whom to produce, the consideration that must be addressed is WHO NEED THE PRODUCT THAT IS TO BE PRODUCED.When a decision has been made about what to produce, the producer must target a particular set of individuals or a specific population of the economy who are going to be the users of the product he want to produce.
