[The evaluation of organ weights by means of multiple regression equations (author's transl)].

The investigation is based on the weights of 570 livers, 648 spleens, 200 right and left lungs, 559 right and 556 left kidneys of 364 male and 360 female persons over 20 years of age being autopsied in our Institute from 1969 to 1972. In both sexes these weights were set in relation to age, body weight, body height, breast width, breast depth and circumference of chest. By the application of higher statistical methods and under computerusage it was made possible to state, that there is a marked relationship between the organ weight on one hand and the body weight and in women the body height on the other. The relationship between the organ weight and various constitutional sizes and age is less marked. In practice these relations should be considered. This can be done by multiple regression equations, which enables us to evaluate the weight of spleen, lungs, kidneys and female livers, but not the weight of the male liver. It must be considered, that the estimated weight of spleen and kidney of both sexes is more inaccurate than that of the lungs of both sexes and of the female livers. The multiple regression equations are tabulated for both sexes (table 4).
