Figure 1 Flow diagram of screening and diagnosing minimal hepatic encephalopathy in high-risk cirrhotic patients. High-risk cirrhotic patients are screened by the inhibitory control test, EncephalApp Stroop App, or critical flicker frequency and are subsequently validated using the psychometric hepatic encephalopathy score (PHES). MHE: Minimal hepatic encephalopathy.
