RESEARCH GUIDE

Find the source. Evaluate the evidence.

This area groups records using publication titles and source-reported publication types. A thematic match is not clinical guidance or expert assessment. Always consult the original study for methods, sample sizes, findings and limitations.

Reading Parkinson systematic reviews and meta-analyses

A systematic review and a meta-analysis describe different features of an evidence synthesis. Check the search strategy, final search date, eligibility criteria and characteristics of included studies. Research published after the search may not be included; the final search date helps establish this boundary.

For a meta-analysis, inspect which studies were combined, compatibility of outcome measures and differences between studies. Risk-of-bias assessment, sensitivity analyses and authors’ limitations are central to interpretation. Do not assume that one pooled numerical result has an identical meaning across all populations or clinical settings. Use publication-type filters to distinguish reviews from original research in this catalog.

  1. Identify the publication type and research question.
  2. Distinguish human, animal and laboratory research.
  3. Assess results and uncertainty from the original text.
  4. Check the source for retractions and corrections.
