[Ratio estimate in medical morphometry (author's transl)].

Abstract

In quantitative morphology the estimates have the form P = S yi/ S xi if the sampling units are unequal or a special constituent of the organ serves as reference. Of interest is the bias of the ratio estimate (P): the stereological investigation of tissue sections through the ventricular wall of hearts of rats following isoproterenol damage revealed that in all cases the bias is unimportant. Therefore it is not necessary to use unbiased estimates.
