Kshirsagar et al. reported that the mean/SD serum albumin levels in HD patients with and without periodontitis (n = 35 and 119, respectively) were 3.83/0.41 and 3.99/0.53 mg/dL, respectively, although this difference did not reach statistical significance (p = 0.06) [33]. The gene discussed is ALB; the disease is periodontitis.
