The slowest part of evidence synthesis is often the first one
Abstract screening can quickly become the most time-consuming stage of an evidence synthesis project.
A broad search strategy may return thousands, tens of thousands, or even hundreds of thousands of records. Human-only screening teams can spend weeks working through records, resolving disagreements, and trying to maintain consistency across reviewers.
For CROs, medcomms agencies, pharma teams, medical device companies, and research groups, this creates familiar problems:
- Projects fall behind before extraction begins
- Internal teams spend too much time on repetitive screening
- Relevant studies may be missed
- Review consistency becomes harder as volume increases
- Large projects become too expensive or impractical
Synthesa helps remove this bottleneck with AI-powered screening workflows and expert validation.
We screen abstracts against your criteria
You provide the research question, search results, and screening rules. Synthesa applies AI-powered workflows and expert review to identify relevant records and produce structured outputs your team can use.
Inputs we can work with
- Search strategy
- Title and abstract records
- PICO criteria
- Inclusion criteria
- Exclusion criteria
- Study design requirements
- Outcome requirements
- Prior screening decisions, where available
- Project-specific instructions
Outputs you receive
- Screened abstract list
- Include / exclude decisions
- Exclusion reason categories, where required
- Records flagged for human review, where needed
- Structured export for your workflow
- Comparison against internal or historical screening results, where applicable
Use Synthesa when screening volume exceeds internal capacity
Overflow screening
support
For CROs and medcomms agencies managing multiple client projects, Synthesa can take on large screening workloads without requiring additional internal headcount.
Parallel screening
validation
Synthesa can screen records in parallel with your human team, allowing you to compare inclusion decisions and evaluate performance.
Retrospective
comparison
If you have a completed review, Synthesa can compare results against prior screening decisions to identify missed relevant records or test workflow performance.
Large-scale
literature sets
For projects with tens or hundreds of thousands of records, Synthesa can screen at a scale that may not be practical for human-only teams.
Free pilot
project
Abstract screening is the preferred starting point for new clients. It is fast, practical, and easy to compare against your existing process.
Start with a free abstract screening pilot
A pilot gives your team a low-risk way to evaluate Synthesa’s screening workflow before committing to a larger evidence synthesis project.
We can run the pilot in one of two ways:
Parallel pilot
Synthesa screens records from a current project while your internal team conducts its usual screening process. You compare the results.
Retrospective pilot
Synthesa screens records from a completed project and compares the results with your prior human screening decisions.
What the pilot includes
- Screening using your defined search strategy and PICO criteria
- Include / exclude decisions
- Structured screened abstract list
- Comparison-ready output
- Delivery within a few days
No new software. No workflow disruption. No internal AI management.
AI screening tools can be useful, but they still require your team to configure the platform, manage the process, check the outputs, and decide how to integrate results into your project workflow.
Synthesa delivers abstract screening as a service.
Your team defines the criteria. We manage the AI-powered workflow, expert validation, and structured output delivery.
AI screening software
- Requires setup and training
- Needs internal workflow management
- Leaves validation burden with your team
- May create adoption friction
- Still requires users to operate the tool
Synthesa abstract screening service
- No software to learn
- No platform implementation
- Criteria-based screening delivered for you
- Expert-reviewed outputs
- Practical pilot available within days
Designed for speed, scale, and consistency
Human screening is essential for judgement, but human-only workflows can struggle when the evidence base becomes too large.
Synthesa combines AI-powered scale with expert review, helping teams screen more records faster while maintaining structured decision logic.
- Handles very large record sets
- Reduces time spent on repetitive screening
- Supports consistent application of criteria
- Helps identify relevant abstracts human-only teams may miss
- Frees specialist teams to focus on interpretation, extraction, synthesis, and client-facing work

Expert review
and quality control built into the workflow
From search results to screened abstract list
1. Define criteria
We align on the research question, search strategy, PICO criteria, inclusion criteria, exclusion criteria, and output format.
2. Run screening workflow
Synthesa applies AI-powered screening workflows to classify records according to your criteria.
3. Expert validation
Evidence synthesis specialists review the screening logic, resolve uncertain cases, and check output quality.
4. Deliver structured outputs
You receive a screened abstract list with clear decisions and, where required, reason categories or comparison-ready fields.
Frenquently Asked Questions
Do we need to use Synthesa software?
No. Abstract screening is delivered as a service. Your team does not need to learn, configure, or manage any software.
Can you use our PICO criteria?
Yes. We screen based on your defined search strategy, PICO criteria, inclusion criteria, exclusion criteria, and project-specific instructions.
Can you work alongside our internal screeners?
Yes. Synthesa can screen in parallel with your team so you can compare decisions.
Can you compare against a completed review?
Yes. For retrospective pilots, Synthesa can compare screening decisions against a completed project.
How quickly can a pilot be delivered?
Pilot results are typically delivered within a few days, depending on record volume and criteria complexity.
What happens after the pilot?
If the pilot is useful, Synthesa can continue with full abstract screening, data extraction, systematic review support, meta-analysis, or broader evidence synthesis work.
Have too many abstracts to screen manually?
Send us your search strategy, criteria, and project context. We can help you decide whether to start with a free pilot, parallel screening support, or a full abstract screening work package.
