My professor demands a systematic review question but I’m lost on framing it correctly?

I have two weeks to turn in the protocol for a systematic review in my epidemiology class, and the rubric insists on a clearly defined research question. I tried brainstorming a few topics, but every draft feels too broad or not specific enough for the PICO format. My instructor also warned that vague questions will lose points, yet I’m not sure how to narrow it down without dropping the main idea. Can anyone show me how to shape a focused question that meets the formatting rules?

Start by forcing your topic into a strict PICO template, but treat each letter as a specific constraint rather than a vague category. The single most effective move is to define your Intervention and Comparison with surgical precision, because that’s where most students lose focus. If you just say “exercise,” it’s too broad; if you specify “30 minutes of moderate-intensity aerobic exercise, three times a week,” you’ve created a searchable, measurable variable. For instance, instead of asking whether diet affects heart health, frame it as whether a Mediterranean diet reduces systolic blood pressure in adults with stage 1 hypertension compared to a standard low-fat diet. This specificity prevents your search from drowning in irrelevant results and makes your inclusion criteria crystal clear for your professor. Once you lock in those four elements, read the sentence aloud to ensure it flows naturally while still hitting every PICO component. If any part feels fuzzy, replace it with a concrete metric or population detail. This approach transforms a sprawling interest into a testable hypothesis that fits the rubric’s demand for clarity. You’ll find that narrowing the scope actually makes the literature search easier, not harder, because you’re targeting specific study designs and outcomes rather than casting a wide, unmanageable net.
