**Selected angle:** `source`

## One-sentence thesis

The cited A/B receipts support a specific working claim: 45.1% of cancer deaths (265,150 of 587,521 deaths) were attributable to evaluated risk factors; Prevalence of SCD increased from 3.9% among adults with no risk factors to 25.0% among those with four or more risk factors. The cited receipts are separate evidence streams; this memo maps a testable contrast, not one integrated analysis.


**Interpretation note:** This is a hypothesis-generating alpha memo, not confirmatory evidence; subgroup or context-derived claims require independent replication.

## Why this is surprising

The deterministic quantification of disease-specific risk factor attributions—such as 90% of strokes from ten factors and 40% of dementia from twelve modifiable ones—reveals a convergent but unsystematized landscape where biomarker integration (e.g., cholesterol efflux capacity, plasma analytes) could bridge predictive gaps across cardiometabolic and neurodegenerative conditions.

Known / obvious (do not republish): 61% of global deaths attributed to GBD 2017 risk factors (fact 170989); 42% of cancers in US adults attributable to evaluated risk factors (fact 93194); Ten risk factors responsible for 90% of strokes (fact 165891)

Real tension: Mediterranean diet improves 18 of 28 MetSyn components (fact 91434) versus EPA-only formulation reducing cardiovascular events by 25% in high-risk patients (fact 36977), indicating potential conflicts in prioritizing dietary versus pharmacological interventions.

## Evidence Landscape

**Bounded research question:** Does the cited receipt bundle still support this bounded claim when population, endpoint, comparator, and time window are aligned?

## Evidence receipts

- `fact_id=93195` (`A_core`) — 45.1% of cancer deaths (265,150 of 587,521 deaths) were attributable to evaluated risk factors. doi=10.3322/caac.21440
- `fact_id=98930` (`A_core`) — Prevalence of SCD increased from 3.9% among adults with no risk factors to 25.0% among those with four or more risk factors. doi=10.15585/mmwr.mm7120a2
- `fact_id=170989` (`A_core`) — Globally, 61·0% (59·6–62·4) of deaths were attributed to the GBD 2017 risk factors. doi=10.1016/s0140-6736(19)31429-1
- `fact_id=142261` (`A_core`) — approximately 40% of dementia cases worldwide could be attributable to 12 modifiable risk factors doi=10.1111/joim.13227
- `fact_id=3160` (`A_core`) — showed an improvement in prediction of cancer death with 5% increase in the C-index in a replication cohort doi=10.1111/acel.13608

## What this changes

Treat this as a focused working signal, not a broad topic claim. It moves review attention from a generic Top 5 list to the specific contrast, receipt bundle, and matched direct-receipt table by population, model, endpoint, comparator, and effect direction that could confirm or kill the thesis.

## Limitations

- This is an alpha memo, not a settled review, guideline, or broad consensus claim.
- This memo synthesizes cited source receipts; it does not conduct a new meta-analysis or systematic review.
- Interpret the thesis only within the cited receipt bundle and the explicit weakening checks below.
- Independent receipts fail to reproduce the claimed contrast.
- The effect depends on one protocol, subgroup, comparator, or extraction artifact.

## What would weaken this

- Independent receipts fail to reproduce the claimed contrast.
- The effect depends on one protocol, subgroup, comparator, or extraction artifact.

## Strongest counter-evidence

- `fact_id=98930` (`A_core`) — Prevalence of SCD increased from 3.9% among adults with no risk factors to 25.0% among those with four or more risk factors. Source: Modifiable Risk Factors for Alzheimer Disease and Related Dementias Among Adults Aged ≥45 Years — United States, 2019
- `fact_id=98929` (`B_context`) — Adults with SCD were more likely to report four or more risk factors than those without SCD (34.3% versus 13.1%). Source: Modifiable Risk Factors for Alzheimer Disease and Related Dementias Among Adults Aged ≥45 Years — United States, 2019

## Next extraction

- Extract independent A_core/B_context receipts that test the lead contrast directly.
- Audit whether each direct receipt remains comparable on population, endpoint, comparator, and measurement method.
