After stratifying ACAG into three tertiles, we observed a dose-response relationship: compared to the reference group (T1, 4.75–14.25), the second tertile (T2, 14.25–18.05) showed a marginally significant increased mortality risk (HR: 1.78, 95% CI: 1.01–3.14, p = 0.0473), while the highest tertile (T3, 18.10–41.50) exhibited a substantially higher mortality risk (HR: 2.17, 95% CI: 1.26–3.77, p = 0.0056).
