Collaboration

Collaborate seamlessly

Systematic reviews are team efforts; the tools should act like it. mapped pairs a 5-role permission hierarchy with blinded dual-reviewer enforcement, Cohen's kappa transparency, threaded chat, and an immutable audit trail — all in one workspace.

Get Started

Updated April 2026

mapped's Collaboration layer gives research teams role-based access (Principal Investigator, Lead Reviewer, Reviewer, Methodologist, Observer), structurally enforced blinded dual-reviewer workflows with automatic conflict resolution, Cohen's kappa inter-rater reliability per phase, threaded project chat with @mentions, direct messaging, a researcher directory, configurable activity notifications, and an immutable audit trail of every screening, extraction, RoB, GRADE, and AI-suggestion decision. Permissions are enforced platform-wide; methodology is enforced by design.

    Just finished my full-text screening pass on Bendary 2024. Flagging it for arbitration — the IVUS protocol is non-standard (no MSA cutoff specified) and follow-up is shorter than our 12-month threshold.

    Agreed, that one's borderline. I'll exclude it and document under "protocol non-standard". Updating the PRISMA flow now.

    FYI on heterogeneity for MACE composite — I² is 71% which is high. We may need to subgroup by lesion complexity (LM/CTO/bifurcation vs all-comers) before locking the random-effects model.

Key Capabilities

Five-Role Team Hierarchy

Principal Investigator (full project control + team management), Lead Reviewer (assigns tasks, resolves conflicts, manages workflow), Reviewer (screens, extracts, assesses), Methodologist (focuses on RoB, meta-analysis configuration, GRADE), and Observer (read-only — supervisors, funders, external auditors). Permissions are enforced throughout the platform; a Reviewer cannot delete a project, an Observer cannot modify decisions.

Blinded Dual-Reviewer Assignment

Cochrane and PRISMA require independent dual review for screening and risk-of-bias. mapped makes it structural, not aspirational. Each reviewer's decisions are blinded until both are complete; disagreements are flagged automatically; a third reviewer or the PI resolves with documented rationale. You can't accidentally skip dual review.

Inter-Rater Reliability (Cohen's Kappa)

Cohen's kappa is calculated automatically per phase (title/abstract, full-text, each RoB tool) and per project. The PI sees a live IRR dashboard alongside per-reviewer throughput — you know when your team is agreeing meaningfully and when reviewers need a calibration session before more screening continues.

Project Chat and Direct Messages

Per-project chat channels with threaded conversations, @mentions, and file sharing — so discussion stays in context, not scattered across email. Direct 1:1 messaging for sensitive topics or quick questions. All chat history is searchable and retained as part of the project's audit-ready documentation.

Immutable Audit Trail

Every screening decision, conflict resolution, data modification, AI suggestion (and acceptance/override), role change, and export event is logged with user, timestamp, and rationale. Entries cannot be edited or deleted. Exportable as part of the supplementary materials — exactly the documentation Cochrane, PRISMA 2020, and journal peer review now require.

Activity Notifications + Researcher Directory

Configurable email and in-app notifications for task assignments, conflicts, milestones, and digest summaries. The researcher directory lets you find collaborators by expertise, institution, or research interest — useful for assembling teams or finding a methodologist for a single project.

Frequently asked questions

What collaboration features does mapped offer?
A 5-role hierarchy (Principal Investigator, Lead Reviewer, Reviewer, Methodologist, Observer), blinded dual-reviewer enforcement, automatic Cohen's kappa IRR, threaded project chat with @mentions, direct messages, a researcher directory, configurable notifications, and an immutable audit trail of every decision.
What's the difference between mapped's roles?
Principal Investigator owns the project and team. Lead Reviewer assigns tasks and resolves conflicts. Reviewer screens, extracts, and assesses. Methodologist focuses on RoB, meta-analysis configuration, and GRADE. Observer is read-only — for supervisors, funders, or external auditors. A user can be PI on one project and Reviewer on another.
How does mapped's collaboration compare to EPPI-Reviewer?
EPPI-Reviewer has solid multi-user collaboration with strong qualitative-coding features. mapped emphasizes blinded dual-reviewer enforcement, Cohen's kappa transparency, and the immutable audit trail — methodology guardrails baked into the workflow. For medical / quantitative reviews with strict PRISMA documentation needs, mapped's structural enforcement is the differentiator.
Can mapped enforce blinded dual review?
Yes — by design. Each reviewer sees the same records but cannot see the other's decisions until both are done. Conflicts are flagged the moment they appear, the resolver sees both rationales, and every step is logged. There is no setting that lets you skip dual review on a phase that requires it.
How much do collaboration features cost?
The Mapped Project tier (list $119/project, currently $79 launch pricing) includes up to 10 collaborators and the full 5-role + dual-reviewer + audit-trail toolkit. The Mapped Team tier (list $199/project, currently $139 launch pricing) adds unlimited collaborators. Custom Enterprise (custom pricing) extends to unlimited team members across unlimited projects, SSO, dedicated onboarding, and an admin console. See mappedresearch.com/pricing.
Is the audit trail editable?
No — it's immutable by design. Entries cannot be edited or deleted by any role. The full trail is exportable as part of supplementary materials, with every screening decision, conflict resolution, data modification, AI suggestion, and role change time-stamped and user-attributed. Exactly what journal peer review and Cochrane now expect.
