Systematic reviews,
from search to forest plot.

Import, screen, extract, appraise and synthesise in one workspace. Every decision is blinded, auditable and reproducible.

A preview of the RevSphere workspace

An example project. Study labels are illustrative, not real citations.

The whole review in one place

Stop stitching four tools together.

Blinded dual screening

Two reviewers decide independently. Neither sees the other until both submit, and conflicts route to an adjudicator.

Extraction that checks itself

Structured templates with field-level validation, dual blinded extraction and conflict resolution on the record.

Risk of bias, guided

RoB 2, ROBINS-I and QUADAS-2 domain judgements with the rationale kept beside each answer.

Synthesis built in

Pairwise meta-analysis, network meta-analysis, diagnostic test accuracy and GRADE certainty.

PRISMA writes itself

The 2020 flow diagram and its counts follow the decisions you have actually made.

The platform

Purpose-built modules for every stage

Three reviewers around a table working a review through its stages: identification, screening, eligibility and included, with a risk-of-bias grid, a data extraction sheet and the bound RevSphere evidence dossier
A reviewer working through record piles at a long table, with a file box labelled Exclusion Reasons beside them

Screening Workbench

Blinded dual screening that keeps reviewers independent until both decide.

  • Two independent reviewers per record
  • Automatic conflict detection
  • Exclusion reasons feed PRISMA live
  • Keyboard-first triage
A master study folder holding every full-text report for one study, with its numbered version history laid out alongside

Study and PDF Management

Publications grouped under studies, with a versioned full-text library.

  • Multiple reports, one study
  • Version history per document
  • Match suggestions with human confirmation
  • Private storage per project
Two reviewers at separate desks completing identical data extraction sheets, a verification and reconciliation folder between them

Dual Blinded Data Extraction

Structured templates filled independently, then verified field by field.

  • Template builder with validation
  • Two extractors work blinded
  • Field-level conflict resolution
  • Verified-value export

Risk-of-Bias Assessment

Domain-based appraisal with judgements you can defend at peer review.

  • Domain and overall judgements
  • Rationale and evidence provenance
  • Traffic-light visualisation
  • Immutable submitted assessments
Reviewer A's Include and Reviewer B's Exclude shown side by side, resolved into a recorded consensus with its full audit trail

Reviewer Conflict Resolution

Every disagreement becomes a tracked decision with a named resolver.

  • Side-by-side reviewer answers
  • Consensus recorded as a new version
  • Original responses never overwritten
  • Full audit trail
A random-effects forest plot with its pooled diamond, beside a network meta-analysis graph and a funnel plot

Evidence Analysis Center

Verified extraction flows straight into analysis — no re-typing.

  • Analysis-ready datasets
  • Meta analysis with human-authorized runs
  • Network meta analysis
  • Publication-bias diagnostics
  • Diagnostic test accuracy
A finished review laid out as a PRISMA flow diagram, a characteristics table, a risk-of-bias summary and a meta-analysis, beside the manuscript itself

Report Generation

Journal-styled outputs assembled from the real state of your review.

  • PRISMA 2020 flow diagram
  • Characteristics tables
  • Export for manuscripts

Trust by design

Evidence you can defend

Blinded by design

Reviewers cannot see each other's work before both submit.

Auditable decisions

Submissions are immutable; corrections create new versions.

Private research data

Per-user security rules and server-side authorisation on every route.

Arabic and English

Full right-to-left interface alongside English.
