{"contradictions": ["The conclusion is that aerobic exercise training effects remains a bounded evidence case: the retained direct, adjacent, and context evidence profile defines the scope for targeted testing, while mixed and null findings limit any unqualified broad clinical claim.", "The corpus contains 13 direct clinical sources, 26 adjacent, review, or context sources, and no sources classified primarily as mechanistic or model-system evidence. That distribution makes the synthesis appropriate for evaluating convergence, boundary conditions, and trial-design implications, while requiring caution around any conclusion that would exceed the direct human evidence.", "Null findings have a specific role in this evidence model. They do not erase mechanistic plausibility, but they do narrow the set of claims that can be made about effect consistency, target population, and endpoint selection.", "The evidence base also distinguishes breadth from certainty. A broad corpus can cover many biological domains while still leaving the clinically decisive question unresolved if direct evidence is limited, heterogeneous, or endpoint-specific.", "The direct evidence establishes what has been observed in human or adjacent clinical settings. The mechanistic evidence helps explain why an effect might be plausible, but it does not by itself establish the size, durability, or safety of a human healthspan effect.", "The study-level structure also prevents selective emphasis. Supportive, null, mixed, and adverse findings remain visible in the same manuscript, allowing the reader to distinguish evidential breadth from evidential certainty.", "Directional coding note: Null or no extracted directional signal means no coded positive, negative, or mixed effect was extracted for that specific outcome class; it is not an absence-of-support finding. Positive, negative, mixed, unclear, and null are outcome-specific codes, so a bounded rationale can be supported by adjacent or different outcome evidence while another outcome remains null or unclear. Contextual claims contain bibliographic background, mechanism, methods, exposure definitions, or population context rather than effect-direction evidence. When an outcome-class summary uses no extracted directional signal, it should state the source proportion, such as X/Y sources, to avoid ambiguity. Majority-direction note: 19/39 retained sources are coded unclear at the receipt level. Unless the extraction records a positive, negative, mixed, or null polarity for the mapped outcome, the manuscript states that direction cannot be determined for that source and narrows the conclusion instead of treating source count as directional support. Directional-map boundary: Because 19/39 retained sources are predominantly unclear-coded at receipt level, the corpus does not support a standalone per-class directional map; source-level p-values and polarity are reported as audit facts rather than efficacy directions unless extraction records polarity.", "Findings Map accounting note: each outcome-class n, direction count, directness count, and source roster is computed from the same source-level rows listed in the detailed table. Receipt-level direction is not a statement that the source abstracts lack directional statistics; it is the conservative coded polarity used for synthesis accounting.
