In other words, IPO and IHO in Japan have hepatitis as a common etiologic factor, and the difference between them lies only in severity and location of fibrosis causing flow resistance; namely, in IHO flow resistance is basically at the postsinusoidal level, while in IPO it is at the presinusoidal level.
