Understanding the Need for Separate Protocols in Title-Abstract and Full-Text Screening stages

In a systematic literature review, the Title-Abstract and Full-Text screening stages serve different purposes, and therefore, often require different protocols or inclusion/exclusion criteria.

Title-Abstract Screening: Broader, Preliminary Evaluation
  • At this stage, reviewers have access only to limited content—typically the title, and abstract.
  • Because of this, the protocol is generally broader to avoid unintentionally excluding potentially relevant studies too early.
  • It helps narrow down the pool of citations for deeper evaluation without missing key studies due to lack of detailed information.

Full-Text Screening: Detailed, In-Depth Assessment
  • Here, reviewers evaluate the entire article, including methods, results, and appendices.
  • This allows for a more specific and refined application of inclusion/exclusion criteria.
  • You can assess nuances such as study design, population subgroups, or the completeness of outcome data.

Example Scenario

Let’s say your objective includes:
  • Including systematic reviews during Title-Abstract screening to ensure a broad capture of literature for bibliographic searches.
  • But at the Full-Text stage, you may decide to exclude those same systematic reviews if your focus is limited to primary studies only.

This flexibility is essential for building a high-quality evidence base without introducing early-stage bias or excluding useful references prematurely.
