Drug Information and Literature Evaluation Flashcards

Which statistical measure describes the spread of data around the mean in a normal distribution?

Answer: Standard deviation

Standard deviation quantifies the dispersion of data points around the mean in a normally distributed dataset.

What type of study design is most appropriate for studying rare adverse drug reactions?

Answer: Case-control study

Case-control studies are ideal for rare outcomes because they start with cases who have the outcome and compare them to controls, requiring fewer subjects.

Which term describes the degree to which a study's results can be applied to patients outside the study population?

Answer: External validity (generalizability)

External validity refers to how well study findings can be generalized to other populations, settings, or time periods.

A meta-analysis combines data from multiple studies primarily to:

Answer: Increase statistical power to detect treatment effects

By pooling data from multiple studies, meta-analyses increase sample size and statistical power, allowing detection of smaller but clinically meaningful effects.

Which type of drug information question requires knowledge of pharmacokinetics and individual patient factors?

Answer: Dosing in renal impairment

Dosing in renal impairment requires integrating pharmacokinetic parameters (e.g., renal clearance) with patient-specific renal function data.

Publication bias in the medical literature most commonly results in:

Answer: Overrepresentation of positive (significant) studies

Publication bias occurs because studies with positive, statistically significant results are more likely to be published, inflating apparent treatment benefits.
