This study aimed at standardizing PHES for Turkish patients and compare them with German norms; to determine minimal hepatic encephalopathy (mHE) prevalence with two different methods [PHES battery and Critical Flicker Frequency (CFF)] and to assess whether sub-tests of the battery can be used for screening for mHE. Healthy volunteers (n = 816; 400 male) and cirrhotics (n = 124; 58 male) were included. For mHE diagnosis PHES score threshold was set at ≤ − 5 points and that of CFF at < 39 Hz. For comparing German and Turkish norms, datasets were combined. Multiple backward procedure was applied to assess effects of age, sex and education on single tests of the battery. Receiver operating characteristic (ROC) curves were created for assessing diagnostic capabilities of subtests of the battery. PHES norms for Turks were developed. MHE prevalence in compensated cirrhotics was 29.8% and 27.4% with PHES and C...

Assessing it is cumbersome.Aims: To standardize PHES for Turkish patients and compare it with German norms; to determine mHE prevalence with two different methods and to assess whether the PHES test can be simplified.Methods: Healthy volunteers (n=816; 400 male) and cirrhotics (n=124; 58 male) were included. PHES score threshold was set at ≤-5 points and that of critical flicker frequency (CFF) at <39 Hz for mHE diagnosis. For comparing German and Turkish norms, datasets were combined. Multiple backward procedure was applied. Receiver operating characteristic (ROC) curves were created for assessing diagnostic capabilities of single subtests of the PHES test. Results: Turkish norms displayed non-linear dependence on age and education. Rate of mHE in compensated cirrhotics was 29.8% and 27.4% with PHES and CFF tests, respec...
