What is the primary difference between a randomized clinical trial and a prospective cohort study?

a) In a randomized clinical trial, patients choose their exposure

b) In a randomized clinical trial, patients are randomly assigned to exposure groups

c) In a prospective cohort study, investigators can never be blinded

d) All of the above

e) None of the above

Expert Solution

Answer: Option C is correct.

Explanation:

In an RCT, investigators randomly assign individuals to different exposure groups.

A cohort study is an observational study.

In a cohort study, the two groups may vary in many aspects as they are exposed to the treatment naturally.

In an RCT, the two groups are more or less similar to each other except for the exposure.

A ["prospective", OR "retrospective"] cohort study is carried out to investigate the association between occupational arsenic inhalation and neurological exposure and neurological effects among workers in a copper smelter. For the sake of simplicity, let’s assume there are two possible exposure categories: high and low (for example, those working in the smelting process and those working in administration). The exposure was carefully assessed by review of company records which reflected very good exposure monitoring (both air sampling and urine testing)....

4S coronary mortality. The Scandinavian simvastatin survival study (4S) was a randomized clinical trial designed to evaluate the effects of the cholesterol-lowering agent simvastatin in patients with coronary heart disease. Over 5.4 years of follow-up, the treatment group consisting of 2221 individuals experienced 111 fatal heart attacks. The placebo group of 2223 individuals experienced 189 such events. Calculate the risks in the groups and test the difference for significance. In relative terms, how much did simvastatin lower heart attack mortality?

In a randomized clinical trial to determine the most effective timing of the administration of chemotherapeutic drugs to lung cancer patients, 26 patients were given four drugs simultaneously, while 15 patients were given the same four drugs sequentially. Objective response to the treatment (defined as the shrinkage of the tumor by at least 50%) was observed in 16 of the patients treated simultaneously and in 4 of the patients treated sequentially.
