CLAIM CARD
The primary within-corpus tension for longevity outcomes stems from the sparse and indirect nature of the evidence. Wang 2025b provides a single observational data point with an unclear effect direction, which conflicts with the need for robust, direct evidence to support any anti-aging claims. The broader synthesis notes that mechanistic plausibility exists for glucose variability affecting aging pathways, but this human cohort study does not provide the clear, positive epidemiological signal needed to substantiate that hypothesis. Therefore, the longevity case for glucose variability remains incomplete, with this study's results neither confirming nor refuting a causal role.
