WHY POSTEROS
Scientific Rigor

Verification isn’t a feature. It’s the architecture.

Every output includes explicit verification status, evidence hierarchy classification, and full reasoning traces. Nothing is hidden.

core architectural principle

How we ensure
accuracy

Every insight is verified using evidence hierarchy and a final human quality gate.

PICO - Structured verification

Evidence hierarchy labeling

Human quality gate

VERIFICATION ARCHITECTURE

Every statement receives an explicit status

No ambiguity. No hidden interpretations. Each scientific claim is assessed against the evidence and assigned a clear status with detailed rationale.

Verified

Drug X demonstrates statistically significant improvement in progression-free survival compared to standard of care.

This claim is unequivocally verified. Three Phase III RCTs (Evidence 12, 23, 45) report consistent PFS benefit with hazard ratios ranging from 0.58–0.67. The 2024 NCCN Guidelines (Evidence 78) cite this as a Category 1 recommendation.

Powered by the Glass Box architecture: The Verification Engine can only assess evidence that has been pre-indexed and audited by upstream agents. It cannot fabricate sources.

Claims specific enough

to verify

Before evidence can be matched, the system decomposes every candidate claim into the PICO framework. This ensures we're verifying the specific assertion-not a vague generalization.

A claim of "superior efficacy" is only verified if the specific Population and Comparator match the evidence. No shortcuts.

P
Population
Adults with advanced NSCLC
I
Intervention
Drug X 150mg once daily.
C
Comparator
Standard platinum-based chemotherapy.
O
Outcome
Progression-free survival (median, months)

EVIDENCE HIERARCHY

Instantly assess the

weight of any reference

Every source in the Evidence Library is classified by study type. This allows instant assessment of evidentiary weight—and ensures your reviewers can quickly identify the strength of support for any claim.

High level
Meta-analysis
Pooled analysis of multiple studies with statistical synthesis.
Randomized controlled trial
Prospective, randomized study with predefined endpoints.
Clinical practice guideline
Expert consensus recommendations (NCCN, ESMO, etc.).
Moderate level
Prospective cohort study
Non-randomized observational study following patients over time.
Real-world evidence
Retrospective analysis of claims, EHR, or registry data.
Low level
Case series / Case report
Descriptive reports without comparator arm.
Expert opinion / Narrative review
Non-systematic expert commentary.

Language neutralization

Promotional language identified automatically

The platform automatically detects subjective or promotional language and refines it into scientifically precise, verifiable statements. No more manual scrubbing.

This isn’t just word-swapping. The system evaluates whether the underlying claim can be supported by the evidence—and adjusts the precision accordingly.

BEFORE

Drug X demonstrates robust efficacy with a dramatic improvement in survival outcomes.

AFTER

Drug X demonstrates statistically significant efficacy with a median OS improvement of 4.2 months (HR 0.68, p=0.01).

Bi - directional mapping

Trace evidence to statement - or the reverse

Every Acceleration Package includes bi-directional traceability. Our system can audit in whichever direction they prefer.

Sources Statement

Click any statement in the document to see exactly which sources support it, with the specific sentences and data points highlighted.

Which evidence supports this claim?
Sources Statement

Click any source in the Evidence Library to see all statements it supports, ensuring no evidence is orphaned or misapplied.

Conflict Identification

When evidence conflicts, we show both sides

General-purpose AI chooses one interpretation and hides the conflict. Posterios flags it explicitly—providing a transparent picture for informed decision-making.

Conflicts are documented in the Reasoning Trace, with explicit notation of which sources diverge and why the final status was assigned.

Evidence conflict detected

Source A (Phase III RCT)

Reports significant PFS benefit (HR 0.58).

Source B (Real-world study)

Reports modest benefit (HR 0.82) in community setting.

Resolution: Statement qualified to specify “in controlled trial settings”.

HUMAN QUALITY GATE

AI generates
Humans validate

Every Acceleration Package passes through a structured scientific validation protocol — a human-in-the-loop step where scientific analysts audit the AI’s work before delivery

Verification audit

Analyst reviews verification statuses and spot-checks rationale against source documents.

Mapping validation

Analyst confirms bi-directional tracing is accurate and no evidence is orphaned.

Final sign-off

Analyst provides scientific sign-off before package is released to client.
