Ebp 1: Essential Ebp Evidence Literacy

1. A good clinical question that will direct a search of the evidence for current, primary research studies consists of an intervention, target population, outcome, and comparison intervention.

True

False

The statement is true. A good clinical question should include the components of an intervention, target population, outcome, and comparison intervention. This helps to focus the search for current, primary research studies and ensures that the question is specific and answerable.

2. Confidence intervals are a measure of clinical significance, and provide a way of estimating where the “true” result for any population lies.

True

False

Confidence intervals are indeed a measure of clinical significance because they provide a range of values within which the "true" result for a population is likely to lie. They take into account the variability in data and provide a level of certainty about the estimated result. Therefore, true is the correct answer.

3. An electronic database such as PubMed can only be accessed from the university library.

True

False

False. An electronic database such as PubMed can be accessed from anywhere with an internet connection. It is not limited to access only from the university library.

False. An electronic database such as PubMed can be accessed from anywhere with an internet connection. It is not limited to access only from the university library.

4. Databases of primary medical literature, such as PubMed/Medline, generally contain a compilation of only high quality evidence.

True

False

The statement is true because databases like PubMed/Medline are specifically designed to include only high-quality evidence from primary medical literature. These databases go through a rigorous process of selecting and reviewing articles before including them, ensuring that the information available is reliable and trustworthy. Therefore, researchers and healthcare professionals can rely on these databases to access credible and evidence-based information for their work.

5. The p-value is a measure of reliability.

True

False

The p-value is not a measure of reliability. It is a statistical measure that helps determine the significance of a hypothesis test. It represents the probability of obtaining the observed data or more extreme data, assuming that the null hypothesis is true. A lower p-value suggests stronger evidence against the null hypothesis, but it does not provide information about the reliability or accuracy of the results.

6. Which study design is best for a study about therapy?

A study about a therapy (intervention) should include a large population (at least 30 subjects), with similar baseline characteristics, meeting tight inclusion and exclusion standards which is then randomly divided into a control (sometimes a "zero" group, often a placebo or comparison intervention) and an experimental or test intervention. The best RCTs contain blinding of subjects, those supplying the intervention, and those analyzing the results.
