For each 1-SD increment, the HRs (95% CIs) for associations of ALB, ALP, TB, TP with incident CD were 0.77 (95% CI 0.71, 0.83, p < 0.001), 1.29 (95% CI 1.19, 1.40, p < 0.001), 0.84 (95% CI 0.77, 0.92, p < 0.001), 0.89 (95% CI 0.82, 0.96, p = 0.002), respectively, while the HRs (95% CIs) for associations of ALB, ALP, TB, TP with incident UC were 0.91 (95% CI 0.86, 0.96, p < 0.001), 1.14 (95% CI 1.09, 1.21, p < 0.001), 0.95 (95% CI 0.90, 1.01, p = 0.080), 1.01 (95% CI 0.96, 1.06, p = 0.67), respectively. This evidence concerns the gene ALB and tuberculosis.
