{"contradictions": ["What does the current evidence establish about Allostatic Load and human geroscience? This synthesis tests the thesis that evidence for Allostatic load is context-dependent, separating outcome-specific signals from broader claims and identifying the evidence gaps that should bound interpretation. Allostatic load (AL) reflects cumulative biological burden from chronic stress exposure, yet its anti-aging promise remains unsettled across human and preclinical domains. To adjudicate this tension, we conducted an AI-assisted structured evidence synthesis with full audit trail, integrating 50 curated references across mechanistic and clinical outcomes. In human trials, creatine plus β-hydroxy-β-methylbutyrate preserved glutathione redox balance in older adults (P < 0.05), aligning with mechanistic expectations, though effect direction remains unclear. Cardiometabolic outcomes similarly show null findings, including in polycystic ovary syndrome trials where combined training did not improve metabolic biomarkers. Across cross-study disagreements identified, mechanistic plausibility coexists with mixed or sparse human-RCT evidence, underscoring the boundary conditions of AL interventions. Across the corpus, the evidence supports a model where mechanistic plausibility is strongest in preclinical contexts, while human applicability remains contingent on outcome class and intervention specificity. Critical gaps include the lack of harmonized AL indices in clinical trials an", "The retained allostatic load corpus is reported by outcome class before any cross-domain interpretation. This structure prevents favorable, null, mixed, and adverse evidence from being blended across biologically different endpoints.", "The immune evidence packet includes 9 source-level summaries and 679 high-confidence observations.
