Understand the topic
A study's design should fit its question. Randomisation can reduce confounding, blinding can reduce some biases, and a comparison group helps interpret an intervention's effects. Each design still has limitations. A systematic review depends on the quality and relevance of the studies it includes.
How to discuss it in Med interview
Summarise the population, intervention or exposure, comparator and outcome. Consider recruitment, sample size, missing data, follow-up, conflicts of interest and whether the findings apply to the patients being discussed. Separate statistical uncertainty from clinical importance. For an article, trace its headline back to what the research actually measured.
Put it into words
A study in a narrow age group may not tell us enough about older patients with multiple conditions. Even a statistically significant result needs interpretation: how large is the benefit, what are the harms, and does it matter to patients?
Common pitfalls
Dismissing an entire study because of one limitation or assuming publication makes a conclusion certain.
