CRP and metabolic syndrome: As shown in Table 4, GrimAge residuals were significantly associated with the MetS factor scores (b = 0.002, β = 0.139, padj < 0.001), CRP (b = 0.020, β = 0.220, padj < 0.001), GGT (b = 0.012, β = 0.161, padj = 0.003), and total measured WBCs (b = 0.167, β = 0.324, padj < 0.001).
