[Consistency analysis in the use of abdominal ultrasonography for diagnosing schistosomiasis japonica-related morbidity].

Objective: To explore the consistency among different indices of abdominal ultrasonography for the diagnosis of schistosomiasis japonica related morbidity and the best combination of the indices.

Methods: Six indices of abdominal ultrasonography were selected to investigate schistosomiasis related morbidity in residents in a village of Hunan Province, and the Kappa coefficients of diagnostic consistency among different indices and Cronbach's alpha coefficients of different combinations of indices were computed.

Results: The Kappa coefficients of 'liver parenchyma > or = grade II' with 'right midclavicular subcostal' and with 'portal vein diameter' were 0.
