How to Combine Keywords and Subject Headings in a Search Strategy
A search strategy is the part of a paper you can actually control when the deadline is close. Before you write a single sentence of your literature review, you decide which concepts matter, which words describe them, and
How to Compare Effect Sizes Across Studies Without Flattening the Differences
Comparing effect sizes is not a sorting exercise. Two studies can report the same standardized number while measuring different constructs, pointing in different directions, following participants for different lengths o
How to Decide Whether a Source Is Strong Enough for a Specific Claim
A source is strong enough for a claim when three things line up: the source type and study design can support the kind of statement you are making, the source addresses the same population, intervention, and outcome as y
How to Decide Which Papers to Skim and Which to Read Deeply
A literature search rarely fails because too few records exist. It fails because the reading queue has no structure. When every record gets the same attention, the papers that actually carry your argument get buried unde
How to Document a Literature Search So Someone Else Can Repeat It
A reproducible literature search is one that a colleague—or a reviewer, or you six months from now—can rerun and land on the same record set. The way to get there is a compact reproducibility log: a single file that reco
How to Extract Population, Intervention, Comparison, and Outcomes Reliably
When you are coding a stack of papers against a PICO framework under a deadline, the hard part is rarely remembering what the four letters stand for. It is deciding, for each study, which sentence actually defines the po
How to Fill Evidence Gaps Before a Research Deadline
A deadline does not change what your sources actually say. What it changes is how you spend the remaining hours. The practical move is to stop writing forward for a moment, list every claim that still lacks a source, ran
How to Find Legal Full Text When a Paper Is Paywalled
A paywall is a routing problem, not a dead end. When a report is due and the key study sits behind a subscription, the fastest safe path is a fixed sequence: confirm the canonical record, check institutional access, look
How to Find Methods Details Hidden in Supplements and Registries
A trial's main paper rarely tells the whole methods story. Planned outcomes, analysis plans, and protocol deviations usually sit in supplements, registration records, and linked reports. For a time-sensitive decision mem
How to Find the Original Study Behind a Claim in a Review Article
A review article compresses dozens of primary studies into a few sentences. When you need to cite, replicate, or challenge one of those sentences, the review is a signpost, not the destination. The task is to trace the r
