ALB and Hepatic cysts: When the participants were divided into three groups according to serum albumin levels, the prevalence of hepatic cysts was significantly higher in the group with low albumin levels: 17.5% for albumin ≥ 4.6 g/dl, 22.0% for albumin 4.3–4.5 g/dl, and 25.1% for albumin ≤ 4.2 g/dl, respectively (Supplementary Fig. 2).
