While the confidence intervals for sensitivity and specificity are wide, due to the small number of liver patients identified in our study, we believe that the major difference between the two studies is in the choice of diagnostic criteria, Screening for hepatopathy by ultrasound alone, as our peers have done, will result in fatal delay or underdiagnosis. For this reason we agree with the conclusion that the diagnosis of FC liver disease must be based on the sum of, clinical, biochemical and ultrasound findings.
