How the directional index works
For each study, an editable weight is calculated as (quality ÷ 100) × (relevance ÷ 100). Direction is coded +1 for supports, 0 for mixed and −1 for contradicts. The index is 100 × sum(weight × direction) ÷ sum(weight), or zero if all weights are zero. It is a descriptive balance of annotations, not an effect estimate.
What it cannot establish
Study independence, publication bias, methodological validity, causal effects, certainty of evidence, confidence intervals or real-world outcomes. Qualitative and quantitative designs are not clinically or statistically comparable by this index. Formal evidence synthesis requires domain-specific procedures.

JSON import replaces the current workspace only after file validation and explicit confirmation. Keep your backup file in a secure location. Changes are saved locally by your browser.
Study quality and provenance
Evidence integrity guidance
A DOI or a source URL is a traceability aid, not proof that the record exists. Quality and relevance scores must be assigned by qualified reviewers according to a documented appraisal process. Duplicate-title and missing-field flags are only reminders for manual inspection.
Technical & methodological safeguards
Reproducible model
All computations are deterministic and documented in the README. No opaque AI scoring or external inference is used.
Privacy by default
No APIs, trackers, authentication, cloud storage or paid services. Persistence relies on localStorage if available.
Careful interpretation
Preloaded studies are expressly fictional, and outputs are not scientific recommendations or validated research conclusions.
