CLAIM CARD
Within the curated corpus, there is a tension in the directness of evidence. The preclinical study by Diego 2024 offers strong mechanistic data on cytokine modulation, while the observational study by Shen 2025 provides only indirect, contextual evidence linking immune factors to vascular aging. Both studies report null or context-dependent overall findings regarding ACE inhibitors as standalone agents for immune aging outcomes. This divergence underscores the current incomplete state of the evidence, where mechanistic plausibility coexists with a lack of direct human trial data on aging-specific immune endpoints.
