ALB and type 2 diabetes mellitus: A one-unit increase in log-transformed, energy-adjusted dietary calcium intake was associated with a decreased risk of T2D (HR = 0.88, 95% CI 0.77, 1.00, p-value = 0.0460) and lower albumin-adjusted serum calcium levels (β = − 0.04, 95% CI − 0.07, − 0.02, p-value = 0.0014).
