Liver disease severity assessed by bilirubin, albumin, international normalized ratio (INR), MELD, and CTP score did not differ between hEtG‐positive LTC and hEtG‐negative LTC (all p > 0.223; Sterneck et al., 2014) and liver disease severity assessed by bilirubin, INR, and MELD score did not differ between patients with low and high hEtG levels (all p > 0.05; Verbeek et al., 2018a). Here, ALB is linked to liver disorder.
