One study used the data as a continuous variable [11], and four studies defined hypoalbuminemia as a common cutoff value (serum albumin level ≤3.5 g/dL) [17,20,21,23], and a significant association with all-cause mortality was found in all these studies (range of HR: 2.497–4.78). The gene discussed is ALB; the disease is Hypoalbuminemia.
