When translating research findings into clinical practice, which step is most critical in the evidence-based practice model?
Answer: Integrating research evidence with clinical expertise and patient values
Evidence-based practice requires integrating the best available research evidence with clinical expertise and individual patient values and preferences.
A nutritionist identifies a statistically significant result (p<0.05) showing that a supplement reduces HbA1c by 0.05%. The clinician should recognize that:
Answer: A small effect can be statistically significant but not clinically meaningful
Statistical significance depends on sample size and does not ensure that an effect is large enough to be clinically meaningful or worth recommending.
Publication bias in nutrition research refers to the tendency for:
Answer: Positive or significant results to be published more frequently than null findings
Publication bias skews the evidence base because studies with null or negative results are less likely to be published, inflating the apparent efficacy of interventions.
In a prospective cohort study examining diet and cancer risk, confounding occurs when:
Answer: A third variable is associated with both the diet exposure and the cancer outcome
A confounder is a variable that is associated with both the exposure and the outcome, potentially creating a spurious or distorted association.
The GRADE system in nutrition research is used to:
Answer: Rate the overall certainty of evidence for specific outcomes across a body of literature
GRADE (Grading of Recommendations Assessment, Development and Evaluation) classifies the certainty of a body of evidence as high, moderate, low, or very low.
Which of the following best describes an 'intention-to-treat' analysis in a nutrition RCT?
Answer: Analyzing all randomized participants in their originally assigned groups regardless of adherence
Intention-to-treat analysis maintains the integrity of randomization by including all participants regardless of protocol adherence, reducing bias.
A nutritionist applies PICO to frame a clinical question. In PICO, the 'C' stands for:
Answer: Comparison or control intervention
In PICO, C stands for Comparison — the alternative intervention or control condition being compared to the primary intervention of interest.
