The following measurements were performed: scar thickness (s) myometrial thickness of the isthmus uteri at the level of the internal cervica los (i) the distance between the scar and the internal cervica losl and the myometrial thickness of fundal neighborhood of scar with interval of scar-isthmus distance (f) (Fig.
While this latter approach may yield prices that are more consistent with demand theory, it can cause a large losl of information when only one price from a set of prices is negative.
