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:
Good question!
The first two questions are very similar. "What should I call you?" is more polite than asking "What can I call you?" but the meanings are the same. These questions are much less common than "What is your name?"
"How can I call you?" is the way you might ask someone for their phone number. "How can I call you," is similar to "How can I get in touch with you?"

The correct answer is letter "B": community and personal valor.
Explanation:
Native Americans is a term referred to the tribes living in what today is the U.S. and Canada before English settlers invaded the continent and occupied their territories mostly by force thanks to the use of firearms. When it comes to religion and values, different native American tribes had different beliefs but all of them had in common the importance of keeping their lands for their communities' wellness.

Answer:
The Principle of closure.
Explanation:
In psychology, Gestalt therapy is a particular type of therapy that has some principles which it works with during therapy.
One of these principles is the principle of closure.
The principle of closure refers to the tendency that the brains has in which it tends to perceive forms and figures in their complete appearance despite the absence of one or more of their parts, either hidden or totally absent. So our brains tend to "complete" the picture when there are missing parts of it.
In the example, a magician has two people concealed in a long wooden box. <u>One person's head and arms stick out </u>of the front and <u>the other's legs stick out </u>of the back. Then the magician saws down the center and <u>it appears that the magician is sawing someone in half. </u>
In this scenario, <u>our brain "completed" the picture, by seeing the head, arms and legs sticking out of the box, it completed the picture and assumed there was just ONE person</u> in the box. Thus, it perceived one person in their complete appearance despite the absence of the rest of the parts.
Thus, this is an example of Principle of Closure
