## The Claim (current version)
## Challenging Evidence
**Source:** Burden of Proof study group, PMC12726400, 41 studies from 1,225 screened
Burden of Proof methodology (designed to correct for publication bias and systematic biases in observational studies) finds social isolation → dementia association has mean RR 1.29 (95% UI 0.981.71) — confidence interval CROSSES 1.0, classifying this as 'possible but uncertain' association. Only 'lack of social activity' sub-measure shows CI that does not cross null (RR 1.34, 95% UI 1.051.71). This contrasts with standard meta-analyses, which have reported hazard ratios for social isolation and dementia ranging from 1.189 (after depression adjustment) to 1.31. The BoP methodology's greater conservatism (specifically correcting for biases that inflate observational estimates) explains the gap between methods.
