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.

Explanation:
Georgia is one of the states that most benefited from Franklin D Roosevelt's New Deal because the President would summer in Warm Springs, Georgia. He knew some of the state's problems first hand. FDR implemented federal programs that paid farmers to stop producing cotton as a means to address the oversupply that was occurring and to raise the price. Roosevelt's intention was to help the tenant farmers and sharecroppers to become self-supporting small farmers and there were some local successes in that the New Deal was the first federal program that concretely helped rural residents to improve their farms and homesteads. Yet the small landowner was still outdone by the larger planters who took advantage of federal funds to mechanize their farms.
