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 first alternative is correct.
Political economy can often be conflicting.
The main instruments of economic policy are monetary policy and fiscal policy. Both can be used to stimulate or discourage the economy. In this way, when they are adopted with the opposite sign, they are an example of conflict, as described in this exercise.
If the government wants to stimulate the economy through increased spending (expansionary fiscal policy), it will be injecting money into the economy. However, the main cause of inflation is excess currency in circulation. Thus, a contractionary monetary policy aims to wipe out the supply of money to contain inflation. That is, the first measure is inflationary to stimulate the economy, but the second is anti-inflationary, however contractionary.
<em>"Suppose the government and the Federal Reserve have conflicting goals. The government wants to encourage economic growth by </em><em>increasing spending</em><em>, but the Federal Reserve wants to decrease inflation by </em><em>decreasing the money supply</em><em>".</em>
