In multivariate analysis, factors that remained predictive of anemia in the final model included duration of dialysis less than 6 months [odds ratio (OR) 3.5, 95% confidence interval (CI) 1.9, 6.5], mean serum albumin < 3.5/3.2 g/dl (BCG/BCP) (OR 3.2, 95% CI 1.8, 5.8) and mean TSAT < 20% (OR 1.9, 95% CI 1.2, 3.2) [7]. The gene discussed is ALB; the disease is anemia (phenotype).
