Search and filter all practical guidesCheck Schema Compatibility Before Combining Repository Exports
Read the declared schema version and preserve new controlled values when importing research metadata.
Align Original and Translated Article Titles
Save language and title role when matching records across multilingual citation sources.
Choose Between Online and Print Publication Dates
Document which publication event determines a review cutoff and retain both dates when available.
Check ORCID Format Before Linking Author Records
Validate the identifier structure and then verify the evidence connecting it to the intended contributor.
Report a Paired Mean Difference
Use the standard deviation of within-person differences and a Student t interval for a paired mean estimate.
Build a Crosswalk Between PMID, PMCID, and DOI
Keep identifier namespaces explicit when joining PubMed citations to articles held in PMC.
Inventory Reuse Permissions for a PMC Text Collection
Record article-level license evidence and separate permitted uses when assembling a text corpus.
Check the Poisson Mean–Variance Assumption
Separate heterogeneous exposure from residual overdispersion before trusting a simple Poisson rate comparison.
Compare Independent Poisson Rates
Check event counts, exposure units, and log-Wald assumptions before comparing two event rates.
Prevent Leakage in Prediction Validation
Keep preprocessing, model selection, and outcome timing inside a reproducible validation design.
Trace a Correction Back to the Extracted Result
Follow linked notices, identify which value changed, and propagate the correction through the review.
Inspect How PubMed Translated a Search
Read the translated query and test whether a field tag or mapped phrase changed the records retrieved.
