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.

Treatment and Management Interpretation

It's a tragic irony that while our arsenal of highly effective MS therapies grows ever more sophisticated, nearly half of eligible patients are missing the shot, often opting out of treatments that can cut relapse rates in half because they fear risks that are statistically dwarfed by the profound, proven benefits of simply taking them.
