How We Build This Report

Primary Source Collection

Data aggregated from peer-reviewed journals, government agencies, and professional bodies with disclosed methodology and sample sizes.

Editorial Curation

Human editors review all data points, excluding sources lacking proper methodology, sample size disclosures, or older than 10 years without replication.

AI-Powered Verification

Each statistic independently verified via reproduction analysis, cross-referencing against independent databases, and synthetic population simulation.

Human Cross-Check

Final human editorial review of all AI-verified statistics. Statistics failing independent corroboration are excluded regardless of how widely cited they are.

Statistics that could not be independently verified are excluded regardless of how widely cited they are elsewhere.

Clinical Presentation and Diagnosis Interpretation

While navigating the often ambiguous and overlapping symptoms of pulmonary embolism, clinicians must become masters of probability, balancing the high sensitivity of modern diagnostics against the sobering reality that no single finding is ever reliably guilty or innocent.
