Grouped by direction: directionally favorable: 4 receipt(s) | other/mixed: 1 receipt(s). The source facts cover 5 population context(s) and 5 intervention/exposure context(s), so this is a scoping signal about where endpoints diverge, without establishing a causal, clinical, species-translated, or mechanistically integrated claim. The listed effect sizes remain source-specific across endpoints and populations; they are not pooled or averaged. This is a heterogeneous indication/context map, not a unified disease-specific or endpoint-family claim. Concrete source-level examples: preadmission metformin use was associated with 39% lower of 30-day mortality (HR = 0.61, 95% CI: 0.46-0.81, p = 0.007); median progression-free survival was 18.0 months (95% CI 14.0-21.6); Metformin is associated with lower mortality in pooled non-adjusted model (OR 0.45 [0.25, 0.81], p = 0.008; I2: 63.9%, p = 0.026).\n\n## Directional grouping\n\n- directionally favorable: metformin_longevity is the intervention/exposure and the reported clinical endpoint favors that arm.\n- comparator/not favorable: metformin_longevity is the comparator arm; the label is limited to that head-to-head endpoint.\n- economic/context only: the receipt reports cost, QALY, or economic context rather than a clinical efficacy endpoint.\n- non-clinical/predictive: the receipt reports descriptive modelling, prediction, or age-clock performance rather than an intervention endpoint.\n- null/non-convergent or other/mixed: the extracted fact is null, mixed, or not directionally interpretable.\n\n- directionally favorable: Association Between Preadmission Metformin Use and Outcomes in Intensive Care Unit Patients With Sepsis and Type 2 Diabetes: A Cohort Study — preadmission metformin use was associated with 39% lower of 30-day mortality (HR = 0.61, 95% CI: 0.46-0.81, p = 0.007)\n- other/mixed: Phase II clinical trial of metformin as a cancer stem cell-targeting agent in ovarian cancer — median progression-free survival was 18.0 months (95% CI 14.0-21.6)\n- directionally favorable: The Effect of Metformin Consumption on Mortality in Hospitalized COVID-19 patients: a systematic review and meta-analysis — Metformin is associated with lower mortality in pooled non-adjusted model (OR 0.45 [0.25, 0.81], p = 0.008; I2: 63.9%, p = 0.026)\n- directionally favorable: Use of metformin and survival of patients with high‐grade glioma — Use of metformin was associated with a significantly better overall and progression-free survival of patients with WHO grade III glioma (HR for OS = 0.30; 95% CI = 0.11-0.81)\n- directionally favorable: Metformin and Cancer Risk and Mortality: A Systematic Review and Meta-analysis Taking into Account Biases and Confounders — Overall cancer incidence was reduced by 31% [summary relative risk (SRR), 0.69; 95% confidence interval (CI), 0.52-0.90]\n\nSpecific moderators in this bundle are population/indication (hospitalized adult COVID-19 patients; nondiabetic patients with advanced-stage epithelial ovarian cancer; patients with WHO grade III glioma (high-grade glioma); patients with diabetes; sepsis patients with type 2 diabetes), study design/evidence type (primary/review). Single primary-study estimates are separated from pooled review or meta-analytic estimates rather than treated as interchangeable.\n\n## Context separation\n\nThe selected receipts group because each carries a fact-level extraction for metformin_longevity; they separate by context (human clinical/observational) and endpoint, so they are not interchangeable evidence for one pooled claim.\n\n## Boundary limits\n\nSource-literature boundary for metformin_longevity: the listed sources define one bounded, context-dependent signal across separate source contexts. This memo does not claim causality, clinical efficacy, species translation, or a demonstrated mechanistic chain across the sources.\n The signal is purely descriptive of effect-direction heterogeneity; it cannot support even a weak causal or comparative-efficacy inference, and pooling across these PICOs would be inappropriate.\n Routing domain `longevity_research` is publication-lane metadata only; the source scope here is defined by the selected metformin_longevity receipts.\n\n## Next gaps\n\nA stronger memo needs one matched PICO: one population, one intervention/exposure, one comparator, and one named outcome.\nIf metformin_longevity is promoted beyond a scoping note, the next run should select sources sharing one context family rather than mixing human clinical/observational.\n","metadata":{"abstract":"This receipt-backed scoping note has one bounded signal: metformin_longevity shows endpoint-specific favorable signals with context limits across this 5-source primary/review bundle (2014-2021).
