Evidence Tracer Infographic
Solving the “Missing PECO” Problem
EviTra is a specialized auditing tool designed to standardize manuscript review by extracting implicit frameworks to reduce inquiry bias.
Extraction Engine
Processes PDF/DOCX using XY-Sorting to filter marginalia and reconstruct multi-column text with XY-coordinate precision.
Linguistic Pre-scan
Employs a Scorch-Earth policy to reject irrelevant metrics (Odds Ratios, P-values) during candidate term extraction.
Bias Diagnostics
Automated detection of Population Drift, Outcome Broadening, and Post-hoc Specification in reporting.
Phase 1: Metadata & Intent
Objective Identification
The auditor first establishes a “Logic Anchor” by scanning the Abstract and Introduction for explicit markers: “The objective of this study…”
Archetype Analysis
Systematic Review
Archetype: Etiology/Risk of Exposure
Context Logic Engine
INFERRED: If Objective is missing, system synthesizes PECO from Methods.

Final Quality Assessment
Level 3
Fragmented Protocol
“Downgrade -1 (Indirectness)”
Major drift detected between Abstract (Humans) and Methods (Rat Models). PECO specification occurred post-hoc.
Red Flag Diagnostics
Explicit
Stated in dedicated section. Action: None.
Implicit
Clear in Inclusion criteria. Action: None.
Fragmented
Scattered elements; minor drift. Action: -1 Grade.
Opaque
Critical elements guessed. Action: -2 or Exclude.
