Enter the two magnitudes you want to compare - for our example, these are 5.8 and 7.1. In 1991, Dr Paul Schnur and his colleagues published an article correlating the weight of breast tissue to be removed in a breast reduction operation with the total body surface area (BSA) of the patient. The Schnur Sliding Scale is widely used by insurance companies in the western United States in the process of preauthorizing breast reduction operations, and its use may be spreading eastward. 4.

This can be instrumental in determining if breast reduction is being planned for a purely cosmetic reason or as a medically necessary procedure. So in small people with large breasts the equation comes out differently obviously than having people larger people with smaller breasts. The Schnur scale had low correlation with actual resection weight ( r2 = 0.381; b1 = 1.153; p < 0.001). Nippon Eiseigaku Zasshi 1968;5:443-50. In order to get the right scale conversion, you need to enter the scale in a box marked "Scale". or Step 2 . 0 with the maintenance need, the glucocorticoid dosing is stated in terms of the For example, you can compare the dimensions of a 5-cm long object to a 100-cm long object.
