A case-control study recruits individuals WITH a condition (cases) and WITHOUT a condition (controls). This design is BEST for studying:
Answer: Rare diseases or conditions with long latency periods
Case-control studies are efficient for rare conditions because they start with known cases and compare retrospective exposure histories with matched controls.
Publication bias in research refers to:
Answer: The tendency for positive results to be published more often than null results
Publication bias skews the available evidence base toward positive findings, as studies with statistically significant results are more likely to be published.
An athletic trainer uses a clinical prediction rule (CPR) that has been validated in a population different from their patient. The MOST appropriate action is to:
Answer: Apply the CPR cautiously while considering differences between populations
CPRs developed in different populations may have reduced accuracy; clinicians should note population differences and apply CPRs with appropriate caution.
Which statistical measure is used to quantify the agreement between two categorical raters beyond chance?
Answer: Cohen's kappa
Cohen's kappa measures inter-rater agreement for categorical variables, accounting for the level of agreement expected by chance alone.
In the context of EBP, patient values and preferences refer to:
Answer: The patient's unique concerns, expectations, and goals regarding their care
Patient values and preferences encompass individual patient goals, concerns, cultural beliefs, and expectations that must be integrated into clinical decision-making.
A study reports a likelihood ratio positive (LR+) of 8.5 for a special orthopedic test. This indicates:
Answer: A positive test result substantially increases the post-test probability of the condition
An LR+ of 8.5 is considered large and substantially shifts the probability of diagnosis toward the condition when the test is positive.
Which research design is MOST susceptible to recall bias?
Answer: Retrospective case-control study
Retrospective case-control studies rely on participants recalling past exposures, making them vulnerable to differential recall between cases and controls.
