- Allow complete information on the subject’s exposure, including quality control of data, and experience thereafter.
- Provide a clear temporal sequence of exposure and disease.
- Give an opportunity to study multiple outcomes related to a specific exposure.
- Permit calculation of incidence rates (absolute risk) as well as relative risk.
- Methodology and results are easily understood by non-epidemiologists.
- Enable the study of relatively rare exposures.

What is the advantages and disadvantages of a pilot survey?
1. It permits preliminary testing of the hypotheses that leads to testing more precise hypotheses in the main study. It may lead to changing some hypotheses, dropping some, or developing new hypotheses. 2. It often provides the researcher with ideas, approaches, and clues you may not have foreseen before conducting the pilot study. Such ideas and clues increase the chances of getting clearer findings in the main study. 3. It permits a thorough check of the planned statistical and analytical procedures, giving you a chance to evaluate their usefulness for the data. You may then be able to make needed alterations in the data collecting methods, and therefore, analyze data in the main study more efficiently. 4. It can greatly reduce the number of unanticipated problems because you have an opportunity to redesign parts of your study to overcome difficulties that the pilot study reveals. 5. It may save a lot of time and money. Unfortunately, many research ideas that seem to show great promise are unproductive when actually carried out. The pilot study almost always provides enough data for the researcher to decide whether to go ahead with the main study. 6. In the pilot study, the researcher may try out a number of alternative measures and then select those that produce the clearest results for the main study.
What is a concurrent cohort study?
it is prospective cohort study
Is cohort study primary or secondary literature?
A cohort study is considered primary literature because it involves original research conducted by the authors.

What is the difference between a panel study and a cohort study?
A panel study involves repeatedly collecting data from the same individuals over time to study changes within the same group. A cohort study follows a group of individuals who share a common characteristic or experience over time to see how their outcomes differ. The key difference is that in a panel study, the same individuals are followed over time, while in a cohort study, different individuals may be added to the study group over time.
In a cohort study a scientist collects health date on a group of drug abusers what characteristic was used to form the cohort?
The characteristic used to form the cohort in this study is drug abuse. The scientist is collecting health data on individuals who share this common characteristic of being drug abusers.
In a cohort study a scientist collects healthy data on a group of drugs abusers what characteristics was used to form the cohort?
The characteristic used to form the cohort in this study would be drug abuse. The cohort would consist of individuals who are drug abusers, and the scientist would collect data on their health outcomes over time to investigate relationships between drug abuse and health.
In a cohort study a scientist collects health data on a group of people born in 1976. What characteristic was used to form the cohort?
The cohort in this study was formed based on the shared characteristic of being born in 1976. This characteristic allows the scientist to follow this group of individuals over time to observe their health outcomes.

Is meta-analysis better than cohort study?
Meta-analysis is not inherently "better" than a cohort study; rather, they serve different purposes. Meta-analysis combines the results of multiple studies to provide a more comprehensive overview of a topic, while a cohort study follows a group of individuals over time to examine the effects of certain exposures. Both study designs have their own strengths and limitations, and their appropriateness depends on the research question being addressed.
