Template

Appraise the clinical study in {study_summary} for whether it should change practice, as a reasoning exercise. (1) Identify the clinical question in PICO terms — population, intervention, comparison, outcome — and check whether the study's actual question matches the one you care about, since a mismatch makes even a perfect study irrelevant to your patient. (2) Assess the design against the question: whether the study type can support a causal claim, and whether randomization, allocation concealment, and blinding were adequate where feasible. (3) Scrutinize the outcomes: are they patient-important (mortality, function, symptoms) or surrogate markers that may not translate to real benefit — a common source of overstated conclusions. (4) Separate statistical from clinical significance: examine the effect size and its confidence interval, the absolute (not just relative) risk difference, and the number needed to treat or harm, because a tiny absolute benefit can be statistically real yet clinically trivial. (5) Judge external validity: do the enrolled patients resemble the population of interest, and were run-in periods or exclusions used that limit generalizability? (6) Weigh harms alongside benefits and note funding or conflict concerns. State whether the evidence warrants a practice change and its strength, emphasizing this appraisal supports clinician judgment and is educational, not medical advice.
