title: Comparable results between standardization methods and regression analysis in predicting mortality rate among samples with burns.
abstract: This report suggests an alternative statistical model for estimating the mortality rate of samples of patients with burns. Three direct standardization methods were applied to nine samples (48,379 patients) selected randomly from the medical literature, and compared with the technique of three regression models, The results showed the similar mortality rates in these samples using the three different methods for standardization in comparison to the rates of LA(50) using three regression models. Of the different standardization methods used to measure the of mortality rate, standardization of death rate for age and area burned may be the best method to objectively evaluate the results of burns care, if combined with LA(50) using regression analysis. Furthermore, the values of LA(50) and 95% Cl in a sample are changed with different regression models. It is necessary to specify the regression model, 95% Cl or correlation coefficient of LA(50) in probit analysis or linear regression, respectively, when LA(50) of one sample is compared with that of another.
